12.

14.Vocabulary Identify the base, exponent, and power in the expression yx.

15. Reasoning Explain why (x y)z = (x z)y but (x y)z ≠ (y x)z.

Answer 1

1 4

2 x-9

3 960

4 x^4y^4 -6x^3y^3

5 a^(7/8)

6 500x^6

7 980

8 6/x

9 ab^5

10 4

11 2x^2

12 6m^(1/2)n^2

14 exponent = power = 1

15 (xy)z = (yx)z. they are not unequal
