Explicación paso a paso:

1. .....

$( {x}^{9} \div {x}^{5} ) \div {( - x)}^{3} \\ ( {x}^{9 - 5} ) \div {( - x)}^{3} \\ {x}^{4} \div {( - x)}^{3} \\ - {x}^{4 - 3} = - {x}^{}$

1. .....
2. $( {25}^{5} \times ( { -4 })^{5} ) \div {( - 10}^{3}) \\ ( {5}^{10} \times {2}^{10} ) \div ( {2}^{3} \times {5}^{3} ) \\ {5}^{10 - 3} \times {2}^{10 - 3} \\ {5}^{7} \times {2}^{7}$
