simplify (r^2)^{-1/2}

Solution

simplify

(r^{2})^{- \frac{1}{2}}

Solution

\frac{1}{r}

Solution steps

(r^{2})^{- \frac{1}{2}}

Apply exponent rule:

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

assuming

a \geq 0

= r^{2 (- \frac{1}{2})}

2 (- \frac{1}{2}) = - 1

= r^{- 1}

Apply exponent rule:

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

r^{- 1} = \frac{1}{r}

= \frac{1}{r}
