simplify (x^{-8})/(x^{-5)}

Solution

simplify

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

Solution

\frac{1}{x ^{3}}

Solution steps

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

Apply exponent rule:

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

= x^{- 8 - (- 5)}

Apply rule

- (- a) = a

= x^{- 8 + 5}

Add/Subtract the numbers:

- 8 + 5 = - 3

= x^{- 3}

Apply exponent rule:

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

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