Answer 2

$\underline{ \underline{ \sf\maltese \: Question}} :$

$\sf \red{if \sqrt{ {3}^{n} } = 27 \: \: then \: 5 \sqrt[n]{64} \: \: is}$

$\underline{ \underline{ \sf\maltese \: Answer}} :$

$\rm{Given}$

$\rm{ \sqrt{ { 3}^{n} } = 27 \: }$

$\rm{ \implies { ({3}^{n}) }^{ \frac{1}{2} } = {3}^{3} }$

$\rm{ \implies \: {3}^{ \frac{n}{2} } = {3}^{3} }$

$\boxed{ \boxed{\sf{ bases \: are \: equal \: so \: powers \: should \: be \: equalised}}}$

$\rm{ \frac{n}{2} = 3} \\ \\ \boxed{\rm{n = 6}}$

$\rm{then \: \: 5 \sqrt[n]{64} = }$

$= 5 \sqrt[6]{64}$

$= 5 \sqrt[6]{ {2}^{6} }$

$= 5(2)$

$= 10$

$\boxed{\boxed{\sf \purple{if \sqrt{ {3}^{n} } = 27 \: \: then \: 5 \sqrt[n]{64} \: \: is \: \: 10}}}$
