Simplify the expression.

Answer: D
Step-by-step explanation:
To solve this problem, we need to know our exponent properties. We know that if you have parenthesis around the exponent, you multiply the exponents.
[tex]\frac{1}{6} *3=\frac{3}{6}=\frac{1}{2}[/tex]
Now that we know the exponent should be 1/2, let's rewrite our expression.
[tex]x^{\frac{1}{2} }[/tex]
