Answer:

A. \frac{x^2\sqrt{x}}{3}

Step-by-step explanation:

We have been given an expression \sqrt{\frac{2x^5}{18}}. We are asked to find which expression is equivalent to our given expression.

Let me simplify our given expression. First of all we will divide 18 by 2 as:

\sqrt{\frac{2x^5}{2\cdot 9}}

\sqrt{\frac{x^5}{9}}

Now we will rewrite x^5 \text{ as } x^4\cdot x.

\sqrt{\frac{x^4\cdot x}{9}}

Now we will write x^4\text{ and } 9 as perfect squares.

\sqrt{\frac{(x^2)^2\cdot x}{3^2}}

Let us factor our perfect square from square-root.

\frac{x^2\sqrt{x}}{3}

Therefore, option A is the correct choice.
