Question

Me ajuda n precisa da A

Answer 1

Oi!

a)

b)
${(\frac{1}{3})}^{5} \\ \frac{1^5}{3^5} \frac{1}{243}$
c)
${(\frac{5}{4})}^{3} \\ \frac{5^3}{4^3} \\ \frac{125}{64}$
d)
Propriedade:
$\boxed{ \sqrt[n]{a^m} = {a}^{\frac{m}{n}}}$

${(\sqrt[3]{5})}^{-3} \\ { ({5}^{\frac{1}{3}} ) }^{-3} \\ {5}^{\frac{- 3}{3}} \\ {5}^{- 1} \\ \frac{1}{5}$
e)
$\frac{ {10}^{-2} \times {10}^{- 3} }{{10}^{- 2}}$

$\frac{ {10}^{(-2 + (- 3))} }{ {10}^{-2} }$

$\frac{ {10}^{(-2 - 3)} }{ {10}^{-2} }$

$\frac{ {10}^{- 5} }{ {10}^{-2} }$

$10^{(- 5 - (-2))}$
$10^{(- 5 + 2)}$
$10^{- 3}$
$\frac{1}{10^3}$
$\frac{1}{1.000}$

Bons estudos!
