Answer:

Step-by-step explanation:
See attachment 1. This is the formula to use.
There are two numbers, so n=2. Plugging them into the formula, you get

Now, putting a 2 in front just means we're finding the square root, so I'll get rid of it. Then, just do the calculation.

The second one is the correct answer
