Answer:

4 *x^2

Step-by-step explanation:

If you have (4x)^2 it wants you to expand your problem and write in a larger form. So k*x^n is 4*x^2. If 4*x^2 is the answer then with out any of the numbers in the original problem it would look like (kx)^n
16 • x^2
you have to square both the constant and the variable. 4^2 is 16 and x^2 is x^2 then multiply together to get 16 • x^2
