factor 3x^{-1}+5x^{-8}

factor

3 x^{- 1} + 5 x^{- 8}

\frac{3 x ^{7} + 5}{x ^{8}}

Solution steps

3 x^{- 1} + 5 x^{- 8}

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

x^{- 1} = x^{- 8} x^{7}

= 3 x^{- 8} x^{7} + 5 x^{- 8}

Factor out common term

x^{- 8}

= x^{- 8} (3 x^{7} + 5)

Refine

= \frac{3 x ^{7} + 5}{x ^{8}}
