Answer:

16a^4

Step-by-step explanation:

You do 4a^2*4a^2= 16a^4 because area of square is length times width and we know that that length and width in a square is equal.

4*4= 16

a^2*a^2= a^4 (because when you multiply powers with the same base like a in this case, you add the powers up. So in this example it would be 2+2= 4)

Put them together to give you 16a^4
