can some one show me how to do this? thanx
use the binomial theorem to show that 7^n + 2 is divisible by 3, where n is a positive integer. (hint: write 7 = 6+1)
OMG, did she come first in all her school assessments?
how long has she been in Australia?
what school are u in?...
such a pity she couldn't get 99.95, otherwise she could do medicine...
can i ask what else did she choose? because she could do Eng Adv, Maths4u...
last year in our school, a girl did ESL, Vietnamese bs, chemistry, Maths4u, then she got 95.00 UAI !!!
well, last year no one finish it. and my teacher told us even the best students can't get everything right. but if you get like 7 out of 8, it's pretty good already,
some very smart guy in our class give up mechanics, they reckon it's too hard.
anyway, it's not possible to finishi the whole eight questions. just curious any one here plan to give up mechanics? is it a wise choice?
