Answer:
Well it is D 16
Explanation:
First of all, 4^2 is 4*4 because it is the power of 2 so you multiply the number by itself 2 times.
For example, I will make a random problem 2^4 some people might think it is 8 but it is not you are supposed to multiply 2 by itself 4 times so it will be 2*2*2*2 which is 16
Hope this helps and hope the example makes sense!
