Question

Simplifique estes radicais.

Answer 1

Resposta:

a) $5\sqrt{5}$     b) $\frac{\sqrt[3]{10} }{4}$

Explicação passo-a-passo:

a) $\sqrt{125} => \sqrt{5^{2}. 5 } => 5\sqrt{^{} 5 }$

$\frac{\sqrt[3]{250} }{20} => \frac{\sqrt[3]{2.5.5^{2} } }{20} => \frac{5\sqrt[3]{2.5^{} } }{20} => \frac{5: 5\sqrt[3]{10^{} } }{20 : 5}=> \frac{1\sqrt[3]{10^{} } }{4}=> \frac{\sqrt[3]{10^{} } }{4}$
