Question

Aplique as próprias convinicentes
$a(3^{2}) \\b(3 ^{2})^{ - 1} \\ c(7 ^{ - 3})^{ - 2} \\ d(2.3.4)^{3}$
​

Answer 1

Explicação passo-a-passo:

conserva base e multiplica os expoentes

$a)~~(3^2)^1=3^{2.1}=3^2\\ \\ b)~~(3^2)^{-1}=3^{2.(-1)}=3^{-2}\\ \\ c)~~(7^{-3})^{-2}=7^{-3.(-2)}=7^6\\ \\ d)~~(2.3.4)^3=2^3.3^3.4^3$
