Answer: option d.

Explanation:

To find the square root of
r^(64), it is important to remember the following:


\sqrt[n]{a^n}=a

Then, knowing this, you can find the square root of
r^(64) with this procedure:


\sqrt{r^(64)}=r^(32)

There is another procedure to solve the exercise. Knowing that:


\sqrt[n]{a}=a^{(1)/(n)}, you get:


\sqrt{r^(64)}=r^{(64)/(2)}=r^(32)

Then the answer is the option d.
