**Problem Statement:**

Find

a) Express the Integration Domain.

b) Find the Partials \(f_x\) and \(f_y\).

c) Find the Area of the Surface using Equation 2.

**Equation 2:**

The area of the surface with equation \(z = f(x, y)\), \((x, y) \in D\), where \(f_x\) and \(f_y\) are continuous, is

\[
A(S) = \iint_D \sqrt{[f_x(x, y)]^2 + [f_y(x, y)]^2 + 1} \, dA
\]

**Task:**

Find the part of the surface \(z = \frac{2}{3} \left(x^{\frac{3}{2}} + y^{\frac{3}{2}}\right)\) that lies above the triangle with vertices (0, 0), (3, 0), and (3, 5).
