The provided image contains a mathematical expression that appears to involve nested fractions and variables. Here's the expression as I interpret it:

$\frac{\frac{x_2}{x_3}}{\frac{\sqrt{x_2}}{1}}$

Simplification Steps:

1. Start by rewriting the expression: $\frac{\frac{x_2}{x_3}}{\frac{\sqrt{x_2}}{1}} = \frac{x_2 / x_3}{\sqrt{x_2}}$

2. Multiply the numerator by the reciprocal of the denominator: $\frac{x_2}{x_3} \div \sqrt{x_2} = \frac{x_2}{x_3 \cdot \sqrt{x_2}}$

3. Combine terms under the square root: $\frac{x_2}{x_3 \cdot \sqrt{x_2}} = \frac{\sqrt{x_2} \cdot \sqrt{x_2}}{x_3 \cdot \sqrt{x_2}} = \frac{\sqrt{x_2}}{x_3}$

Final Answer:

$\frac{\sqrt{x_2}}{x_3}$
