Question

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.

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.
