Answer 2

Step-by-step explanation:

$\bf \underline{Given-}$

$\sf{ \bigg( \frac{3}{5} \bigg) ^{4} \times \bigg( \frac{8}{5} \bigg) ^{ - 12} \bigg( \frac{32}{5} \bigg) ^{6} }$

$\bf \underline{To\: find-}$

$\textsf{Simplify the given fractional expression and find their value.}$

$\bf \underline{Solution-}$

$\textsf{Given fractional expression,}$

$\sf{ \bigg( \frac{3}{5} \bigg) ^{4} \times \bigg( \frac{8}{5} \bigg) ^{ - 12} \bigg( \frac{32}{5} \bigg) ^{6} }$

$\sf{ \Rightarrow \: \frac{ {3}^{4} }{ {5}^{4} } \times \bigg( \frac{5}{8} \bigg) ^{12} \times \frac{(32 {)}^{6} }{ {5}^{6} } }$

$\sf{ \Rightarrow \: \frac{ {3}^{4} }{ {5}^{4} } \times \bigg( \frac{5}{8} \bigg) ^{12} \times \frac{( {2}^{5} {)}^{6} }{ {5}^{6} } }$

$\sf{ \Rightarrow \: \frac{81}{ {5}^{4} } \times \frac{ {5}^{12} }{ {8}^{12} } \times \frac{ {2}^{30} }{ {5}^{6} } }$

$\sf{ \Rightarrow \: \frac{81 \times {5}^{12} \times {2}^{30} }{ {5}^{4 + 6} \times ( {2}^{3} {)}^{12} } }$

$\sf{ \Rightarrow \: \frac{81 \times {5}^{12} \times {2}^{30} }{ {5}^{10} \times {2}^{36} } }$

$\sf{ \Rightarrow \: \frac{81 \times {5}^{12 - 10} }{ {2}^{36 - 30} } }$

$\sf{ \Rightarrow \: \frac{81 \times {5}^{2} }{ {2}^{6} } }$

$\sf{ \Rightarrow \: \frac{81 \times 25}{64} }$

$\sf{ \Rightarrow \: \frac{2025}{64} }$

$\bf \underline{Answer-}$

$\bf{\underline{{Hence, the \: value \: of : \: \bigg( \frac{3}{5} \bigg) ^{4} \times \bigg( \frac{8}{5} \bigg) ^{ - 12} \bigg( \frac{32}{5} \bigg) ^{6} } \: is \: \frac{2025}{64} }.}$
