Question

(2)-³,(3)-⁴,(-4)-²,(1/4)-³

Answer 1

Vamos là.

(2)^-3 = 1/8

(3)^-4 = 1/81

(-4)^-2 = 1/16

(1/4)^-3 = 64

Answer 2

Explicação passo-a-passo:

${2 }^{ - 3} = \frac{1}{ {2}^{3} } = \frac{1}{8} \\ \\ {3}^{ - 4} = \frac{1}{ {3}^{4} } = \frac{1}{81} \\ \\ {( - 4)}^{ - 2} = \frac{1}{ {( - 4)}^{2} } = \frac{1}{16} \\ \\ {( \frac{1}{4}) }^{ - 3} = {4}^{3} = 64$
