Question

Evaluate the exponent expression for a = –2 and b = 3.

Answer 1

Answer:

- 9/8

Explanation:

-2a^-3b^2/a where a = -2 and b = 3

-2(-2)^-3(3)^2/(-2)

-2(- 1/8)(9)/(-2)

-2(- 9/8)/(-2)

9/4/(-2) or…

2.25/(-2)

-1.125 or - 9/8

Answer 2

The choose B) -9/8

Explanation:

`\frac{ - 2a ^( - 3 ) {b}^(2) }{a} \\ \frac{ - 2( - 2)^( - 3) {3}^(2) }{ - 2} \\ ( - 2(9))/( - 2( - 8)) = - (9)/(8)`
