Question

please answer this step by step with formula​

Answer 1

Step-by-step explanation:

1)

$({a}^{m} ) {}^{n} = {a}^{mn}$

$(( { \frac{8}{3} })^{4} ) {}^{ - 2} = ( \frac{8}{3} ) {}^{ - 8}$

$( {a})^{ - n} = \frac{1}{ {a}^{n} }$

$({ \frac{3}{8} })^{8}$

2)

${a}^{m} \times {b}^{m} = {a}^{mn}$

$( { \frac{12}{5} } \times \frac{25}{18}) ^{ - 5}$

$({ \frac{10}{3} })^{ - 5}$

$({ \frac{3}{10} })^{5}$
