Question

Se ⁵√125=x,qual é o valor de x³?​

Answer 1

$\sqrt[5]{125}=x\\\\x=\sqrt[5]{125}\\\\x=\sqrt[5]{5^3}$

---------------------------------------------------------------------------------------------------

$\\x^3=(\sqrt[5]{5^3})^3=\sqrt[5]{5^{3\cdot3}}=\sqrt[5]{5^9}=\sqrt[5]{5^{5+4}}=\sqrt[5]{5^5\cdot5^4}=\sqrt[5]{5^5}\cdot\sqrt[5]{5^4}=5\sqrt[5]{5^4}$

Answer 2

Resposta: ${x}^{3} = \sqrt[5]{ {5}^{3} } = 5 \times 5 \times 5 = 125$
