Question

I dont understand how to simplify an expression with exponents

Answer 1

3^4

Explanation:

Simplifying an expression with expression with exponents:

If they are dividing, we keep the base and subtract the exponents. For example:

`(a^x)/(a^y)=a^(x-y)`

In this question:

`(3^2)/(3^(-2))=3^(2-(-2))=3^(2+2)=3^4`
