Answer 2

$\underline{ \underline{{ \huge{ \textbf{ \textsf{Ꮪᴏʟᴜᴛɪᴏɴ :-}}}}}}$

------------------------

$: \longrightarrow \tt \blue{ \: \frac{ {5}^{ - 7} \times ( - {2)}^{3} }{2 \times {5}^{ - 5} } }$

------------------------

Now, bring those numbers to the denominator whose power is in negative value.

$: \rightarrow \tt \orange{ \: \dfrac{ \dfrac{1}{ {5}^{7} } \times - 8 }{2 \times \dfrac{1}{ {5}^{5} } } }$

$: \rightarrow \tt \orange{ \: \dfrac{ \dfrac{ \cancel1}{ {5}^{7} } \times - \cancel8 \: ^{4} }{ \cancel{2} \times \dfrac{ \cancel{1}}{ {5}^{5} } } }$

$: \rightarrow \tt \orange{ \: \dfrac{ {5}^{7} \times - 4 }{ {5}^{5} } }$

Now, we know that the numbers whose base are same while division , their powers will be subtracted.

$: \rightarrow \tt \orange{ \: {5}^{7 - 5} \times - 4}$

$: \rightarrow \tt \orange{ \: {5}^{2} \times - 4 }$

$: \rightarrow \tt \orange{ \:25 \times - 4}$

$: \rightarrow \boxed{\tt \orange{ \: - 100 \: \: or \: \: \dfrac{1}{100} } \: \: \: \: (ans)}$
