Question

answer the 6th Q plz

Answer 1

Hope u like my process
=====================
a)

$( {16}^{( - \frac{1}{5}) } ) \\ = {( \frac{1}{16} )}^{ \frac{1}{5} } \\ = \sqrt[5]{ \frac{1}{ {2}^{4} } } \\ = \sqrt[5]{ \frac{2}{ {2}^{5} } } \\ = \frac{ \sqrt[5]{2} }{2} ....answer..$
b)

$( {(343)}^{ \frac{1}{3} } )^{ - 2} \\ = {( \sqrt[3]{343} )}^{ - 2} \\ = {( \frac{1}{ \sqrt[3]{ {7}^{3} } } )}^{2} \\ = {( \frac{1}{7}) }^{2} \\ = \frac{1}{49}$
Hope this is ur required answer
