Step-by-step explanation:

1. The negative exponent indicates that (3²)² is actually in the denominator, thererfore,, you can rewrite the expression as it is shown below:

2.By the properties of exponents you raise a powers of powers, you must multiply the exponents shown, then:

3. Then. you obtain that the equivalent expression is:

Option c is correct

Step-by-step explanation:

We are given an expression and we find its equivalent by solving it
