Question

Fourth root 81 - 3*cubth root 27+5*fifth root 32

Answer 1

$\huge\bf\blue{Right-Question➠}$

$\sqrt[4]{81} - \sqrt[3]{27} + \sqrt[5]{32}$

$\large\bf\green{Solution➽}$

$( {81}^{ \frac{1}{2} } )^{ \frac{1}{2} } \times {27}^{ \frac{1}{3} } \times \sqrt[5]{32}$

${9}^{ \frac{1}{2} } \times ( {3}^{3} )^{ \frac{1}{3} } \times \sqrt[5]{32}$

$3 \times 3 \times ( {2}^{5} )^{ \frac{1}{5} }$

$3 \times 3 \times 2$
