Solution steps

\frac{- 3 ^{5}}{- 3 ^{8}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

= \frac{- 3 ^{5 - 8}}{- 1}

Subtract the numbers:

5 - 8 = - 3

= \frac{- 3 ^{- 3}}{- 1}

Apply the fraction rule:

\frac{- a}{- b} = \frac{a}{b}

= \frac{3 ^{- 3}}{1}

Apply rule

\frac{a}{1} = a

= 3^{- 3}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{1}{3 ^{3}}

3^{3} = 27

= \frac{1}{27}
