Question

Select the equivalent expression.
(2^-4 x z^-3)^5 =
Choose 1 answer:

Answer 1

A

Explanation:

`(2^(-4)z^(-3))^(5)`

several ways to approach this.

use power rule.
`(a^(m) )^(n) = a^(mn)`

`(2^((-4*5))z^((-3*5)) )`

`(2^(-20) z^(-15) )`

RULE:
`x^(-1) = (1)/(x)`

`(1)/((2^(20)z^(15)) )`
