Resposta:
Explicação passo a passo:
a) (-9)² . (-9)³=
[tex](-9)^{2 + 3}[/tex] =
[tex](-9)^{5}[/tex] =
(-9) . (-9) . (-9) . (-9) . (-9) = - 59049
b)(7-1)⁴ =
[tex]6^{4}[/tex] =
6 . 6 . 6 . 6 = 1296
c) 6-¹ . 6⁵ =
[tex]6^{- 1 + 5}[/tex] =
[tex]6^{4}[/tex] =
6 . 6 . 6 . 6 = 1296
d) (–1/2)⁴ . (–1/2) =
(–1/2)⁴ . [tex](-1/2)^{1}[/tex] =
[tex](-1/2)^{4 + 1}[/tex] =
[tex](-1/2)^{5}[/tex] =
(–1/2) . (–1/2) . (–1/2) . (–1/2) . (–1/2) =
- 1 / 32 = - 0, 03125
