Some consider 0 as a perfect square but some not, because some ppl definite perfect square as square of a POSITIVE INTEGER. If not wrong, the syllabus in our text book doesn't include 0 as a perfect square. The answer should be B.

according to the question, it only needs perfect square that is below 8. Thus the perfect square that meet this requirement is 1 (1^2) and 4 (2^2)....the next perfect square is 9 (3^2) and cannot be included

is there any rule or fixed pattern when answering physic, chemistry and bio paper 2 essay questions and paper 3 experiment

anyone can help solve this question?

QUESTION: find the range of X if |X| < 3

my answer is X < 3 or X>-3 ,answer sheet is gone == and cannot check whether it is correct or not

but if we take out the modulus sign , isn't it the X can be both negative and positive

I think X can only be either negative or positive, but not both, so, the answer should be x<3 or x>-3...do you agree?

yea sure..tq

ha..terima kasih ya =D

because FE is the normal line to the DEGH plane thus the correct 1 is FGE

add math still got 5 more chapters haven't read yet D=

just draw out the earth and determine through the picture...it is an easy chapter if you master the drawing =)

lolx......I think the trigo. is the hardest chp........need a lot of memorizing skill

I think add.math's passing mark in spm is quite low bar...

C for credit ~

A for excellent? lolx i am not so sure about that

i think 85 and above bar........70 looks too low for A+...anyway it is my personal opinion =S

so easy then can A+ ??

if like that....then i can skip all F5 chp and safely get at least A-


yea......thats why I am keep doing those add math question......must get A+ aaaaaa

lolx......I even haven't start my mod. math.....what I worry is my moral and physics

mod. math I tonight read through then ok ler confident enough to score very high mark.........physics never touch, later going to read too.....going to plan my time well =o=
