$x^2+16x+64$

This is due to the fact that if you separate it, you will get $(x+8)(x+8)$ . I'm going to assume your teacher taught you how to FOIL.

So you FOIL it out, and you get

$x^2 + 8x + 8x + 64$

Then you combine like terms giving you

$x^2 + 16x + 64$

How do you simplify (x + 8)^2(x + 8)^2?
