when a value is outside of the root, then you can square it and put it back in. After you put it back in, you need to multiply it by the number that is remaining
In this case, you would square 10 which equals 100, and put it back into the root and multiply 100 by 5.
100x5=500
Therefore, the answer is A, root 500
