simplify (x^{-1})^3

Solution

simplify

(x^{- 1})^{3}

Solution

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

Solution steps

(x^{- 1})^{3}

Apply exponent rule:

(a^{b})^{c} = a^{b c},

assuming

a \geq 0

= x^{- 1 \cdot 3}

Multiply the numbers:

1 \cdot 3 = 3

= x^{- 3}

Apply exponent rule:

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

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

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