simplify (x^{-2/3})^2

Solution

simplify

(x^{- \frac{2}{3}})^{2}

Solution

\frac{1}{x ^{\frac{4}{3}}}

Solution steps

(x^{- \frac{2}{3}})^{2}

Apply exponent rule:

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

assuming

a \geq 0

= x^{- \frac{2}{3} \cdot 2}

- \frac{2}{3} \cdot 2 = - \frac{4}{3}

= x^{- \frac{4}{3}}

Apply exponent rule:

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

x^{- \frac{4}{3}} = \frac{1}{x ^{\frac{4}{3}}}

= \frac{1}{x ^{\frac{4}{3}}}
