Answer:
[tex](3x)^{\frac{1}{2})[/tex]
Step-by-step explanation:
Taking the square root of a term is the same as raising it to the 1/2 power.
The expression that we're taking the square root of is under the radical. In this question, that is 3x. This means we raise 3x to the 1/2 power; this gives us
[tex](3x)^{\frac{1}{2})[/tex]
