Question

Responda a letra A e B urgente !! quem souber .

Answer 1

a) $\sqrt[4]{3 \sqrt{5} }=\ \textgreater \ \sqrt[4]{ \sqrt{3^2*5}}\\\sqrt[4]{ \sqrt{9*5}} =\ \textgreater \ \sqrt[4]{ \sqrt{45}} =\ \textgreater \ \sqrt[4*2]{45} =\ \textgreater \ \sqrt[8]{45}$

b) $\sqrt[3]{2 \sqrt{2^4} } =\ \textgreater \ \sqrt[3]{ \sqrt{2^2*2^4} }=\ \textgreater \ \sqrt[3]{ \sqrt{2^{2+6}}} \\ =\ \textgreater \ \sqrt[3]{ \sqrt{2^6} }= \sqrt[3*2]{2^6}\\ = \sqrt[6]{2^6} =2$
Espero ter ajudado :)
Lembre-se de marcar a melhor resposta ^^

Answer 2

A= $\sqrt[4]{3 \sqrt{5} }=\ \textgreater \ \sqrt[4]{ \sqrt{3^2*5}}\\\sqrt[4]{ \sqrt{9*5}} =\ \textgreater \ \sqrt[4]{ \sqrt{45}} =\ \textgreater \ \sqrt[4*2]{45} =\ \textgreater \ \sqrt[8]{45}$
 
B$\sqrt[3]{2 \sqrt{2^4} } =\ \textgreater \ \sqrt[3]{ \sqrt{2^2*2^4} }=\ \textgreater \ \sqrt[3]{ \sqrt{2^{2+6}}} \\ =\ \textgreater \ \sqrt[3]{ \sqrt{2^6} }= \sqrt[3*2]{2^6}\\ = \sqrt[6]{2^6} =2$
