What is the squate root of r^64



need help ....
a r^4
b r^8
c r^16
d r^32

Answer 1

8*8 equals 64 and a square root is a number times another number equals thr number that you are going for

Answer 2

Answer: option d.

Step-by-step 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:

$\sqrt[n]{a}=a^{\frac{1}{n}}$, you get:

$\sqrt{r^{64}}=r^{\frac{64}{2}}=r^{32}$

Then the answer is the option d.
