The question that have is to simplify and write the answer in exponential notation using positive exponents 2 to 4th power x 2 -2

These are my choices

a 4 to the 8th power
b 2 to the 8th power
c 4 to the 2nd power
d 2 to the 2nd power

1. helper

2 to 4th power x 2 -2 ?

2^4 * 2^(-2)

If so,
2^4 = 16
2^(-2) = 1/(2^2) = 1/4

2^4 * 2^(-2) = 16 * 1/4 = 16/4 = 4

4 = 2^2
