12. Your friend evaluates the power (-3)^2Is your friend correct? Explain.

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
