simplify 1/(x^{-3)}

Solution

simplify

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

Solution

x^{3}

Solution steps

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

Apply exponent rule:

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

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

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

Apply the fraction rule:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

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

Apply the fraction rule:

\frac{a}{1} = a

= x^{3}
