Question

\sqrt[5]{2,43 \times 10^{-3}}

Me ajudem a resolver essa questão, urgentemente!!!

Answer 1

Olá!
 
    $\sqrt[5]{2,43\cdot 10^{-3}}=\sqrt[5]{243\cdot 10^{-2}\cdot 10^{-3}} = \sqrt[5]{243\cdot 10^{-5} }=\\ \\ (243\cdot 10^{-5})^{\frac{1}{5}} = (3^5)^{\frac{1}{5}}\cdot 10^{\frac{-5}{5}} = 3^{\frac{5}{5}}\cdot 10^{-1} = 3\cdot \dfrac{1}{10} = \\ \\ = \dfrac{3}{10} = 0,3.$



Bons estudos!
