Question

Define powers provide an example of power with an exponent of 2

Answer 1

Well not sure what you are asking, but If it is what I think it is, it would go like this: 
          2 
(9^2)

Then the answer should be 

9^4 since we multiply the exponents. 

If you mean this...

3^2....It would be same as 3 x 3 which we should know is equal to nine. 

Hope I helped! (Be sure to thank me!)

Answer 2

Well, the power of a number is how many times you multiply a number by itself. Such as, 3 squared, or 3 to the power of 2, would be
3 x 3, which equals 9.
