simplify (x^{-4})/(x^{-2)}

Solution

simplify

\frac{x ^{- 4}}{x ^{- 2}}

Solution

\frac{1}{x ^{2}}

Solution steps

\frac{x ^{- 4}}{x ^{- 2}}

Apply exponent rule:

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

= x^{- 4 - (- 2)}

Apply rule

- (- a) = a

= x^{- 4 + 2}

Add/Subtract the numbers:

- 4 + 2 = - 2

= x^{- 2}

Apply exponent rule:

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

= \frac{1}{x ^{2}}
