simplify sqrt(a^r)

Solution

simplify

a^{r}

Solution

a^{\frac{r}{2}}

Solution steps

a^{r}

Apply radical rule:

a = a^{\frac{1}{2}}

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

Apply exponent rule:

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

assuming

a \geq 0

= a^{r \frac{1}{2}}

Simplify

r \frac{1}{2} : \frac{r}{2}

= a^{\frac{r}{2}}
