Answer 2

concept

we know that

$a {}^{m} \times a {}^{n} = a {}^{m + n}$

and

$\frac{a {}^{m} }{a {}^{n} } = a {}^{m - n}$

step by step explanation

$\frac{5 {}^{m} }{5 {}^{ - 3} } = 5 {}^{5}$

$5 {}^{m} \times 5 {}^{3} = 5 {}^{5}$

$5 {}^{m + 3} = 5 {}^{5}$

on comparing

m+3 = 5

therefore

$m = 2$
