Answer 1

Answer:

$\frac{ {5}^{3} }{ {5}^{7} } \\ \frac{5 \times 5 \times 5}{5 \times 5 \times 5 \times 5 \times 5 \times 5 \times 5} \\ \frac{1}{5 \times 5 \times 5 \times 5 } \\ \frac{1}{625}$

Answer 2

Solution :-

$\rightarrow\sf \: \frac{ {5}^{3} }{ {5}^{7} } \\ \\ \bf \: using \: \frac{ {a}^{m} }{ {a}^{n} } = {a}^{(m - n)} \\ \\ \rightarrow\sf \: {5}^{(3 - 7)} \\ \\ \rightarrow\sf \: {5}^{( - 4)} \\ \\ \bf \: using \: {a}^{( - m)} = \frac{1}{ {a}^{m} } \\ \\ \rightarrow \boxed{ \bf\frac{1}{ {5}^{4}}}$
