Question

a)2-¹ b)(½)-¹ c)(-2)-³ d)(-2)-³ e)(½)-¹ f)(-½)-⁴ g)(-½)-⁴​

Answer 1

Explicação passo-a-passo:

$a) {2}^{ - 1} = \frac{1}{2}$

$b) {( \frac{1}{2}) }^{ - 1} = 2$

$c) {( - 2)}^{ - 3} = \frac{1}{ {( - 2)}^{3} } = \frac{1}{ - 8} = - \frac{1}{8}$

$d) - \frac{1}{8}$

$e)2$

$f) {( - \frac{1}{2} )}^{ - 4} = {( - 2)}^{4} = 16$

$g)16$
