Credits to : Zarinar , Kenny , Jomin and Yuan Yi !
All this hassle just to help a particular Sec 1 girl with her Sec 1 Maths Question !!
And finally said thank after a LONG time (:



Tiffany.C Madeline says:
Hey Chocolate ! You free ?

Zarinar ! says:
sort of
why ? (:

Tiffany.C Madeline says:
Can help my Sec 1 with a Maths question ?
She needs help
I'll link you girls up ?
Express question

Zarinar ! says:
add her to the conversation (:

Tiffany.C Madeline says:
Okay(:

Zarinar ! says:
goodie not free o.o ?

Tiffany.C Madeline says:
He's not home ):

Zarinar ! says:
o:
out with aaron ?

Tiffany.C Madeline says:
Amelia , type the question again
Yeah

Zarinar ! says:
hellos (: whats that question ?

Tiffany.C Madeline says:
hence fid the smallest positive integer m such that 1400m is aperfect square

I think its this one
This is question B

Zarinar ! says:
huh ?

Tiffany.C Madeline says:
Umm ..
Hold on arh
express 1400 as aproduct of its prime factors, giving your answer in index notation
tis is A
B
hence fid the smallest positive integer m such that 1400m is aperfect square

This is the full question
The answer for A is 1400 divide 2 = 700
700 divide 2 = 350
350 divide 2 = 175
175 divide 5 = 35
35 divide 5 = 7
lalala says:

2^3 X 5^3X7

This is confusing

Zarinar ! says:
okok
i get it .
then ?
she needs help in B uhs ?

Tiffany.C Madeline says:
Yeah

Zarinar ! says:
w8 uhs

Tiffany.C Madeline says:
Amelia , learn from her

lalala says:
ok

Tiffany.C Madeline says:
Don't just think bout the answer okay ?

Zarinar ! says:
hehe , i ask people x:

Tiffany.C Madeline says:
Learn the method

lalala says:
sori that i use caps juz now...

Tiffany.C Madeline says:
Hahas (: Okay
Thanks chocolate (:

Zarinar ! says:
ur welcome (:

Tiffany.C Madeline says:
Amelia , did you jot down the method from question A ?
Then you can learn so next time you know how to do (:

lalala says:
yes

Tiffany.C Madeline says:
Good good (:

Zarinar ! says:
goodie
i mean
chocolate *
hehe X:

Tiffany.C Madeline says:
Hahas

Zarinar ! says:
whats the answer for part A again ?

Tiffany.C Madeline says:
The answer for A is 1400 divide 2 = 700
700 divide 2 = 350
350 divide 2 = 175
175 divide 5 = 35
35 divide 5 = 7
2^3 X 5^3X7

Zarinar ! says:
wrong
is 2^3 x 5^2 x 7

lalala says:
2^3 x 5^2 x 7
rite?

Zarinar ! says:
yea

lalala says:
but b?

Zarinar ! says:
w8

Tiffany.C Madeline says:
..
Really ?
Calculation wrong I guess
Cause I got that from ANOTHER FRIEND
Heehees (:

Zarinar ! says:
hahahaha
okok (:

Tiffany.C Madeline says:
Lol(:

Zarinar ! says:
ur friend know how to do mahs ?

Tiffany.C Madeline says:
Which friend ?

Or the one in the conversation ?
Umm
I think my friend don't know

Zarinar ! says:
the one in the conversation

Tiffany.C Madeline says:
Nope
All don't know
You know ?
Omg

Zarinar ! says:
??

Tiffany.C Madeline says:
I asked like a gazillion people just to help her with this question
..
lol
I'm confused myself

Zarinar ! says:
w8w8

Tiffany.C Madeline says:
lol

Zarinar ! says:
ur friend in this conver. is amelia right ?
she know how to do part a mahs ?

Tiffany.C Madeline says:
Yeap(:

Zarinar ! says:
okays (:

Tiffany.C Madeline says:
Amelia ..
You know how to do part A ?

lalala says:
yes

Tiffany.C Madeline says:
Ah .. you talk to her

lalala says:
ok

Zarinar ! says:
okays
so you know how to do uhs ?

lalala says:
u mean A or B

Zarinar ! says:
A

lalala says:
i know

Zarinar ! says:
okays

lalala says:
?
Zarinar ! says:
nth

Tiffany.C Madeline says:
lol
Random Math Conversation

Zarinar ! says:
m=2x7
=14

lalala says:
correct
hw u get th answer?

Tiffany.C Madeline says:
..
Amelia , you mean you KNEW how to do ?

Zarinar ! says:
lols !!

Tiffany.C Madeline says:
...

lalala says:
no

Tiffany.C Madeline says:
...

lalala says:
i dunno

Tiffany.C Madeline says:
Oh ...
OMG ! Scared the hell outta me !

lalala says:
but ny teacher tell me th answer

Tiffany.C Madeline says:
...
But not the method ?

lalala says:
i mean to the whole class
4 checking

Tiffany.C Madeline says:
So you guys must find the answers and method yourself la ?

lalala says:
yea

Tiffany.C Madeline says:
..
Err ..
Okay
So you got the method
Done right ?

lalala says:
so cn tell me th expplaation

Tiffany.C Madeline says:
......................

lalala says:
or i mean juz explain

Tiffany.C Madeline says:
She just typed just now

Zarinar ! says:
.___.

Tiffany.C Madeline says:
-.-
m=2x7
=14

lalala says:
no

Tiffany.C Madeline says:
Thats the method ..

lalala says:
but i wan to understang

Tiffany.C Madeline says:
..........

lalala says:
y is it 2x7
uderstand

Tiffany.C Madeline says:
..................
Errrrr ....
WAIT !

lalala says:
understand

Zarinar ! says:
??
Tiffany.C Madeline says:
Umm ..

lalala says:
yes?

Tiffany.C Madeline says:
Can you like ...

Zarinar ! says:
so you understand mahs amelia ?

lalala says:
not realli

Zarinar ! says:
okays w8

lalala says:
i dun understand hw 2 cn x7
w8?

Tiffany.C Madeline says:
Understand how to get by studying the whole method and answers and stuff ? Thats how I learn Maths (:
When I don't understand

lalala says:
but whe i know th answer i still duno hw

Zarinar ! says:
the prime is
2^3 x 5^2 x 7
so when we square root.
the power must be in even.
so 5 the power already 2
then 2 the power is 3
not even
so we make it even
by times a 2
and then
the 7
noly got power 1
need power 2
so we tkae 7 times 2
so it will be 2 ^ 4 x 5 ^ 2 times 7 ^ 2
so all the power is in even number.
where we can square root it.

Tiffany.C Madeline says:
The method studying

Zarinar ! says:
just know when we break down into prime factors.
when we want to square them.
the prime factors the power need to be in even power.
can ?

Tiffany.C Madeline says:
Wow
( mouth open big big )

Zarinar ! says:
hahah
amelia understand ?

lalala says:
wait...
at first...
2^3 x 5^2 x 7
,
Tiffany.C Madeline says:
........

lalala says:
dhe bcum...
5^2 x2^4 x 7^2
so th answer should b 19600

Zarinar ! says:
huh ?

Tiffany.C Madeline says:
Isn't the whole explanation there ?
^^^^
lalala says:
n after finding th square should b 140
rite

Tiffany.C Madeline says:
...

lalala says:
ok

Tiffany.C Madeline says:
OVERALL !
Do you understand ?
...

Zarinar ! says:
amelia understand ?

lalala says:
a little...

Zarinar ! says:
hmm
i ask my friend explain

lalala says:
ok...

Zarinar ! says:
kenny
explain

KENNNY. I just dont like you,suckers. says:
i thought 1 only?

Zarinar ! says:
amelia
listen to kenny

lalala says:
ok

KENNNY. I just dont like you,suckers. says:
i need charge money sia.
so many.
LOL.

Zarinar ! says:
lols XD
roflrofl

KENNNY. I just dont like you,suckers. says:
ermms.
amelia?

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
did you get the first part right?
you shld get 2^3 x 5^2 x 7 right.

lalala says:
yeah

KENNNY. I just dont like you,suckers. says:
okay.
then let's just break up the power.
for instant, 2^3
try square root-ing it.

lalala says:
gt decimals

KENNNY. I just dont like you,suckers. says:
okay.
then we try 2^4

lalala says:
no remainder
ans 4

KENNNY. I just dont like you,suckers. says:
okay.
then we try again
2^5
try square root.

lalala says:
gt remainder

KENNNY. I just dont like you,suckers. says:
okay,
then we try 2^6

lalala says:
no remainder

KENNNY. I just dont like you,suckers. says:
okay.
so frm that
we can conlude.
powers that are in odd numbers like 2^3, 2^5 give us decimals right?

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
whereas powers taht are in even like 2^4, 2^6 give us a whole number uhs?
that*

lalala says:
yea

KENNNY. I just dont like you,suckers. says:
so therefore in order to square this 2^3 x 5^2 x 7.
we need all power in even right.
5 is already in even.

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
2 is not in even.
neither is 7
so we times 2 and 7.
to make it 2^4 x 5^2 x 7^2

lalala says:
ok
dhen square root it?

Zarinar ! says:
no need .

lalala says:
?

KENNNY. I just dont like you,suckers. says:
cause.
qn ask what is m ma.

lalala says:
ok
so?

KENNNY. I just dont like you,suckers. says:
okay.

Zarinar ! says:
so 7 x 2 = 14 lo

KENNNY. I just dont like you,suckers. says:
i let me part time tutor teach you.
go zarinar(:
my*

Zarinar ! says:
hahaha

lalala says:
OKAY!

Zarinar ! says:
? .__________.
chill x.x
so you still dont understand sermo ?

lalala says:
y 7 x 2?

Zarinar ! says:
cause you see arhs ,

lalala says:
i under stand in another way

Zarinar ! says:
then ?

lalala says:
lyk 2^4 x 5^2 x 7^2
equal to 19600
then 19600 divided by 1400
equal to 14

KENNNY. I just dont like you,suckers. says:
yupps.
you can think it that way.
but you know why must be 2^4 x 5^2 x 7^2
you know anot?

lalala says:
yeah

KENNNY. I just dont like you,suckers. says:
cause we need all powers to be even.
then can square root.

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
okay amelia

lalala says:
but why still must b2 x 7

KENNNY. I just dont like you,suckers. says:
how about i ask you to think in this manner.
qn say is
1400 times m must be a perfect square right.
perfect square means a whole number, no decimals right?

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
okay, from what i said just now,
in order to have a whole number,
all powers need to be even.
from the part A you do.
you got this.
2^3 x 5^2 x 7

lalala says:
yea

KENNNY. I just dont like you,suckers. says:
not all powers are in even right?

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
so we got to make it even.
so how do we make it even?
by mutliplying them right?

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
so what numbers do we need to multiple
so we can get this 2^3 x 5^2 x 7

lalala says:
2 n 7

KENNNY. I just dont like you,suckers. says:
yea.
like that lo
okay
i give you another example.
2^7 x 5^2 x 7^3
now i ask you to perfect square this.

lalala says:
ok

KENNNY. I just dont like you,suckers. says:
what number we need to multiple to make the powers even?

lalala says:
we need to mutiply 2 n 7

KENNNY. I just dont like you,suckers. says:
yupps.
okay
1 more qn.

lalala says:
ok

KENNNY. I just dont like you,suckers. says:
3^3 x 7^5 x 2^3
perfect square this.
what number do we need to multiple?

Zarinar ! says:
3 x 7 x 2 = 42
is it ? o.o

lalala says:
yes

Zarinar ! says:
xD

KENNNY. I just dont like you,suckers. says:
wei.
i asking the amelia leyy.

Zarinar ! says:
hehe

KENNNY. I just dont like you,suckers. says:
i know you know la zarinar, TT.

lalala says:
lol

KENNNY. I just dont like you,suckers. says:
later she dont know.

Zarinar ! says:
i be sec 1 for awhile la x.x

KENNNY. I just dont like you,suckers. says:
okay,

Zarinar ! says:
ask her again (:

KENNNY. I just dont like you,suckers. says:
amelia 1 more qn.
zarinar SHHHHHHHHHHHH.
*zips her mouth*

Zarinar ! says:
*struggles*

lalala says:
yr scondary wad?

KENNNY. I just dont like you,suckers. says:
amelia, 11^3 times 13^2 times 7^3
now perfect square this amelia.
*double zips zarinar mouth !*

lalala says:
multiply 11 n 13 n7

KENNNY. I just dont like you,suckers. says:
amelia
think again.
we need the powers to be even.

lalala says:
11n 7

KENNNY. I just dont like you,suckers. says:
yupps !
that's it !
13 is already in the power of even nubmers.
there's no need for you to times 13 again.
so you know how to do?
ermms zarinar.

Zarinar ! says:
*cries*

lalala says:
yes

Zarinar ! says:
?

KENNNY. I just dont like you,suckers. says:
you think you can take over frm here?

lalala says:
but another ques...
eg

KENNNY. I just dont like you,suckers. says:
yea ameelia?

lalala says:
2 x 5^3x 11

KENNNY. I just dont like you,suckers. says:
yeaa.
so you see
2 is actually the same as 2^1 (if you dont believe check your cal)

Zarinar ! says:
lols !!

KENNNY. I just dont like you,suckers. says:
so 1 is a odd number right?

lalala says:
yes

KENNNY. I just dont like you,suckers. says:
so we have to times 2
to make it 2^
which can be square root.

lalala says:
dhen 4 11 we nid to multiply to?

KENNNY. I just dont like you,suckers. says:
huh?

lalala says:
sori

KENNNY. I just dont like you,suckers. says:
for you mean?
okay,
similary,
11 also can be write as 11^1 ( you can check your cal again)

lalala says:
ok

KENNNY. I just dont like you,suckers. says:
smilarly*
so it's also in the power of odd.

lalala says:
so we chang eth power to even

KENNNY. I just dont like you,suckers. says:
we need to make it even.
ypupps(:
there you go.

lalala says:
so 5^3 must multiply to rite?

KENNNY. I just dont like you,suckers. says:
yupps.

Zarinar ! says:
yea

KENNNY. I just dont like you,suckers. says:
cause it's in odd.
okay.
amelia.
one very last qn.

lalala says:
ok

KENNNY. I just dont like you,suckers. says:
2^2 timesx 3^2 times 5^2
perfect square root this.
what numbers do we need to mutliply?

lalala says:
no number?

KENNNY. I just dont like you,suckers. says:
yuppps(:
you understand le.
my job is done.

lalala says:
okay
wait yr all wad sec?
