Answer:
B. 2
Step-by-step explanation:
So when we are dealing with exponents identify the following terms
Base: the number being multiplied by itself
Exponent: the number of times you multiply the base number by itself
So in this problem we would have to find what x is in order to find our exponents, you can do this by substiting each number for x and solving as is
[tex]3^4=3*3*3*3=81[/tex]
[tex]9^2=9*9=81[/tex]
