Answer 4

Oh, I see. It's already to be put in the sum of two cubes form.

Answer 5

Thanks!

Answer 6

Yes. :D

Answer 7

I just get confused on the first factor with such a large exponent :P

Answer 8

Sorry, I meant,\[a^3 + b^3 = (a + b)(a^2 - ab + b^2)
\]

Answer 9

Yeah, gotta make sure to remember the slight differences between the two similar cube equations for my quiz tomorrow!
