Question:- Find

$\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}$

Taking power inside the bracket

$\frac{5^{4} }{ {12}^{4} } \times \frac{ {12}^{3} }{ {15}^{3} }$

$\frac{ {5}^{4} }{ {12}^{4 - 3} } \times \frac{1}{ {(5 \times 3)}^{3} } \\ \frac{ {5}^{4} }{12} \times \frac{1}{ {5}^{ 3 } \times {3}^{3} } \\ \frac{ {5}^{4 - 3} }{12 \times {3}^{3} } \\ \frac{5}{4 \times 3 \times {3}^{3} } \\ \frac{5}{4 \times {3}^{4} } = \frac{5}{4\times81 } \\ Answer- \frac{5}{324}$

$Power\:Form- \frac{ 5 }{12 \times {3}^{3} }$
