The expression in the image is:

$\frac{\sqrt{x^3 y}}{\sqrt{x y^3}}$

Let's simplify this step by step.

Step 1: Combine the radicals

Both the numerator and the denominator are square roots. We can combine the entire expression under one square root:

$\frac{\sqrt{x^3 y}}{\sqrt{x y^3}} = \sqrt{\frac{x^3 y}{x y^3}}$

Step 2: Simplify the fraction inside the square root

Now, simplify the fraction:

$\frac{x^3 y}{x y^3} = \frac{x^{3-1} y^{1-3}} = x^2 y^{-2}$

Step 3: Apply the square root

Now apply the square root to each part:

$\sqrt{x^2 y^{-2}} = \sqrt{x^2} \cdot \sqrt{y^{-2}} = x \cdot y^{-1}$

Since $y^{-1} = \frac{1}{y}$, the final result is:

$\frac{x}{y}$

Thus, the simplified expression is:

$\frac{x}{y}$
