Answer:

(D)
$\sqrt{(r^(32))^(2)}=r^(32)$

Explanation:

Given:
$\sqrt{r^(64)}$

To find: The square root of
$\sqrt{r^(64)}$ .

Solution: The given equation is:

$\sqrt{r^(64)}$ , on simplifying the given equation, we have

$\sqrt{(r^(32))^(2)}$

Now, taking the square root on both the sides, we get

$\sqrt{(r^(32))^(2)}=r^(32)$

Thus, from the given options, option D is correct that is
$\sqrt{(r^(32))^(2)}=r^(32)$
