Answer 2

Answer:

A

Step-by-step explanation:

In this problem, first u would have to keep the base of 3, then multiply the two powers together to get -28.

However, u can't leave a negative power in the numerator, so u bring the base and the power down into the denominator, change the sign of the power to make it positive, and put a 1 in the numerator.
