$64 x^{2} + 64 x y + 16 y^{2}$ $64x^2 + 64xy + 16y^2$

Explanation:

You can rewrite ${(8 x + 4 y)}^{2}$ $(8x+4y)^2$ to $(8 x + 4 y) (8 x + 4 y)$ $(8x+4y)(8x+4y)$
Then multiply each number with another (expand the brackets) to get $64 x^{2} + 32 x y + 32 x y + 16 y^{2}$ $64x^2 +32xy + 32xy + 16y^2$ which can be simplified to $64 x^{2} + 64 x y + 16 y^{2}$ $64x^2 + 64xy + 16y^2$
