[tex] \sf Q) {[ {2}^{ - \frac { 1}{2} } . {7}^{ \frac{1}{3} }] }^{6} = {?} [/tex]
[tex]\sf \implies {( {2}^{ \frac { \frac{1}{1} }{2} } . {7}^{ \frac{1}{3} }) }^{6} [/tex]
[tex] \sf \implies {( \frac{ {7}^{ \frac{1}{3} } }{ {2}^{ \frac{1}{2} } } )}^{6} [/tex]
[tex] \sf \implies \frac{ {7}^{2} }{ {2}^{3} } [/tex]
[tex] \sf \implies \frac{49}{8} [/tex] is the required answer.
