Answer:

no , see below

Step-by-step explanation:

when you raise a number to a power, you multiply the number by itself the amount of times the power is. so if (-3) has a power of 2 , we multiply -3 by itself twice.

so we get -3 × -3

a negative times a negative is a positive

so -3 × -3 = 9 , not -9
