Answer 1

${\huge{\underline{\mathtt{\orange{Solution:–}}}}}$

$\implies { (- 4)}^{ - 3} \times {(5)}^{ - 3} \times { (- 5)}^{ - 3}$

$\implies { (- 4 \times 5)}^{ - 3 + (- 3)} \times {( - 5)}^{ - 3}$

$\implies {( - 20)}^{ - 6} \times { (- 5)}^{ - 3}$

$\implies { (- 20 \times - 5)}^{ - 3 + ( - 6)}$

$\implies {(100)}^{ - 9}$

$\implies {( \frac{1}{100}) }^{9}$
