Answer 1

a) $\frac{3}{\sqrt{3} }$

$\frac{3}{\sqrt{3} }\times \frac{\sqrt{3} }{\sqrt{3} }$

$\frac{3\sqrt{3} }{\sqrt{3}\sqrt{3} }$

$\frac{3\sqrt{3} }{3}$

$\sqrt{3}$

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

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

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

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