Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{a)\:\sqrt[\mathsf{5}]{\mathsf{8,1^4}} = 8,1^{4/5}}$

$\mathsf{b)\:\sqrt{\mathsf{\pi ^3}} = \pi ^{3/2}}$

$\mathsf{c)\:\sqrt[\mathsf{6}]{\mathsf{\left(\dfrac{1}{7}\right)^4}} = \left(\dfrac{1}{7}\right)^{4/6} = \left(\dfrac{1}{7}\right)^{2/3} = 7^{-2/3}}$

$\mathsf{d)\:\sqrt[\mathsf{8}]{\mathsf{(\sqrt{8})^3}} = \sqrt[\mathsf{8}]{\mathsf{8^{3/2}}} = 8^{3/16}}}$

Answer 2

Resposta:

a)

(81/10)^(4/5)

b)

pi^(3/2)

c)

(7)^(-4/6) =7^(-2/3)

d)

[8^(3/2)]^(1/9)

=8^(3/18)

=8^(1/6)

=(2³)^(1/6)

=2^(3/6)

=2^(1/2)
