Question

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

Answer 1

no

Explanation:

(- 3)² = - 3 × - 3 = 9 ≠ -9

Answer 2

no , see below

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
