Question
**Problem Statement:**

Let \( R \) be the region in the first quadrant of the \( xy \)-plane bounded by the hyperbolas \( xy = 1 \), \( xy = 4 \), and the lines \( y = x \), \( y = 9x \). Use the transformation \( x = \frac{u}{v}, \, y = uv \) with \( u > 0 \) and \( v > 0 \) to rewrite the integral below over an appropriate region \( G \) in the \( uv \)-plane. Then evaluate the \( uv \)-integral over \( G \).

\[
\iint_R \left( \sqrt{\frac{y}{x}} + \sqrt{xy} \right) \, dx \, dy
\]
