Answer 2

$\boxed{ \underline{ \underline{\footnotesize\tt{ \: Solution:-} }}}\: \purple{\: ♬}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\purple \leadsto\footnotesize \tt{4 \times 81 ^{ \frac{ - 1}{2} } (81^{ \frac{1}{2} } + 81 ^{ \frac{3}{2} })}$

$\purple \leadsto \footnotesize \tt{4 \times ({9}^{2}) ^{ \frac{ - 1}{2} } (( {9}^{2}) ^{ \frac{1}{2} } + ({9}^{2} ) ^{ \frac{3}{2} })}$

$\purple \leadsto \footnotesize \tt{4 \times ({9}^{ \cancel2}) ^{ \frac{ - 1}{ \cancel2} } (( {9}^{ \cancel2}) ^{ \frac{1}{ \cancel2} } + ({9}^{ \cancel2} ) ^{ \frac{3}{ \cancel2} })}$

$\purple \leadsto \footnotesize \tt{4 \times {9}^{ - 1} (9 + { {9}^{3} } )}$

$\purple \leadsto \footnotesize \tt{4 \times \frac{1}{9} (9 + { {9}^{3} } )}$

$\purple\leadsto \footnotesize \tt{4 \times \frac{1}{9} (9 + 729)}$

$\purple \leadsto \footnotesize \tt{4 \times \frac{1}{9} ( 738)}$

$\purple \leadsto \footnotesize \tt{4 \times \frac{1}{ \cancel9} \times \cancel{ 738 }}$

$\purple\leadsto \footnotesize \tt{4 \times82}$

$\boxed{ \underline{ \underline{ \purple \leadsto\footnotesize\tt{ 328} }}}\: \purple{\: ♬}$
