Answer 1

Explicação passo-a-passo:

a.

$\frac{7}{ \sqrt[8]{{3}^{5} } } \times \frac{ \sqrt[8]{ {3}^{3} } }{\sqrt[8]{ {3}^{3} }}$

$\frac{7\sqrt[8]{ {3}^{3} }}{\sqrt[8]{ {3}^{5} }\sqrt[8]{ {3}^{3} }}$

$\frac{7 \sqrt[8]{27} }{ \sqrt[8]{ {3}^{5} \times {3}^{3} } }$

$\frac{7 \sqrt[8]{27} }{ \sqrt[8]{ {3}^{8} } }$

$\frac{7 \sqrt[8]{27} }{3}$

b.

$\frac{4}{ \sqrt[6]{5} } \times \frac{ \sqrt[6]{ {5}^{5} } }{ \sqrt[6]{ {5}^{5} } }$

$\frac{4 \sqrt[6]{ {5}^{5} } }{ \sqrt[6]{5} \sqrt[6]{ {5}^{5} } }$

$\frac{4 \sqrt[6]{3125} }{ \sqrt[6]{5 \times {5}^{5} } }$

$\frac{4 \sqrt[6]{3125} }{ \sqrt[6]{ {5}^{6} } }$

$\frac{4 \sqrt[6]{3125} }{5}$

c.

$\frac{9}{ \sqrt[7]{ {3}^{5} } } \times \frac{ \sqrt[7]{ {3}^{2} } }{ \sqrt[7]{ {3}^{2} } }$

$\frac{9 \sqrt[7]{ {3}^{2} } }{ \sqrt[7]{ {3}^{5} \sqrt[7]{ {3}^{2} } } }$

$\frac{9 \sqrt[7]{ {3}^{2} } }{ \sqrt[7]{ {3}^{5} \times {3}^{2} } }$

$\frac{9 \sqrt[7]{ {3}^{2} } }{ \sqrt[7]{ {3}^{7} } }$

$\frac{9 \sqrt[7]{ {3}^{2} } }{3}$

$3 \sqrt[7]{ {3}^{2} }$

$3 \sqrt[7]{9}$

d.

$\frac{6}{ \sqrt[5]{ {14}^{2} } } \times \frac{\sqrt[5]{ {14}^{3} } }{\sqrt[5]{ {14}^{3} } }$

$\frac{6\sqrt[5]{ {14}^{3} } }{\sqrt[5]{ {14}^{2} }\sqrt[5]{ {14}^{3} } }$

$\frac{6 \sqrt[5]{2744} }{\sqrt[5]{ {14}^{3} \times {14}^{2} } }$

$\frac{6 \sqrt[5]{2744} }{ \sqrt[5]{ {14}^{5} } }$

$\frac{6 \sqrt[5]{2744} }{14}$

$\frac{3 \sqrt[5]{2744} }{7}$
