Question

raiz cubica de 20 dividido por raiz cubica de 400

Answer 1

$\sqrt[3]{20} \div \sqrt[3]{400} \\ \sqrt[3]{20 \div 400} \\ \sqrt[3]{0.05} \\ \sqrt[3]{ \frac{1}{20} } = \frac{1}{ \sqrt[3]{20} } \times \frac{ \sqrt[3]{ {20}^{2} } }{ \sqrt[3]{ {20}^{2} } } = \\ \frac{ \sqrt[3]{ {20}^{2} } }{20} \\ \frac{ \sqrt[3]{400} }{20} = \frac{2 \sqrt[3]{50} }{20} = \frac{ \sqrt[3]{50} }{10}$
