Answer 1

Nope. don't treat the statement inside to be seperable.

Answer 2

Are you familiar with Pacal's triangle?

Answer 3

(a+b)*(a+b)*(a+b)

start foiling

Answer 4

foiling?? and no I dont

Answer 5

do you know how to do

(a+b)*(a+b) = a^2 + 2ab+b^2?

Answer 6

so now we have (a+b)*(a^2+2ab+b^2)

Answer 7

its not 2 it's 3?

Answer 8

(a+b)^3 = (a+b)*(a+b)*(a+b) =(a+b)*(a^2 + 2ab+b^2)

Answer 9

I don't get it. the first part would be a^3+b^3=

Answer 10

no

(a+b)^3 does not equal a^3+b^3

Answer 11

example

(2+2)^3 = 4^3 = 64
but
2^3+2^3 = 16
