Question

Simplify The Following: ​

Answer 1

Solution:-

To find:-

$\frac{ ( {\frac{3}{5}) }^{ - 7} }{ ( {\frac{3}{5}) }^{ - 5} }$

By the Problem:-

$\frac{ ( {\frac{3}{5}) }^{ - 7} }{ ( {\frac{3}{5}) }^{ - 5} } \\ = > ( {\frac{3}{5}) }^{( - 7) - ( - 5)} \\ = >( {\frac{3}{5}) }^{( - 7) + 5} \\ = > ( {\frac{3}{5}) }^{ - 2} \\ = > ( {\frac{5}{3}) }^{ 2} \\ or \\ = > \frac{25}{9}$

Formula:-

$i) \: \frac{ {a}^{b} }{ {a}^{d} } \\ = > {a}^{(b - d)}$

$ii) \: ({\frac{1}{a} )}^{ - b} \\ = > {a}^{b}$
