Answer: E) x^5

=====================================================
Step-by-step explanation:
We simply take half of the exponent 10 to get 5. This applies to square roots only.
So the rule is

A more general rule is
![\sqrt[n]{a^b} = a^(b/n)](https://img.qammunity.org/2022/formulas/mathematics/college/ny91tw8iwsopavio7lyg0wevqh9mjl84j6.png)
If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.
