Question

escreva usando um radical simples raiz 5 de a ² sobre raiz 3 de a ?

Answer 1

46 ea de cinco e a de 3 e 19

Answer 2

$\dfrac{ \sqrt[5]{ a^{2} } }{ \sqrt[3]{a } } = \dfrac{ \sqrt[15]{ (a^{2})^{3} } }{ \sqrt[15]{a^{5}} } = \sqrt[15]{ \dfrac{(a^{2})^{3}}{a^{5}} } = \sqrt[15]{ \dfrac{a^{6}}{a^{5}} } = \sqrt[15]{ a^{6-5}} = \sqrt[15]{ a}$
