Question

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

Answer 1

Answer:

A

Step-by-step explanation:

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

2^-20 * z^-15

1/2^20 * z^15

Answer 2

Answer:

A

Step-by-step 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:  $x^{-1} = \frac{1}{x}$

$\frac{1}{(2^{20}z^{15}) }$
