Question
**Problem Statement:**

Given \( f(x, y) = 2x^6 + 5x^2y^5 - 3y^2 \), find:

1. \( f_x(x, y) = \) _____
2. \( f_y(x, y) = \) _____
3. \( f_{xx}(x, y) = \) _____
4. \( f_{xy}(x, y) = \) _____

**Explanation:**

This problem involves finding the partial derivatives of the function \( f(x, y) \).

- \( f_x(x, y) \) is the partial derivative of \( f \) with respect to \( x \).
- \( f_y(x, y) \) is the partial derivative of \( f \) with respect to \( y \).
- \( f_{xx}(x, y) \) is the second partial derivative of \( f \) with respect to \( x \).
- \( f_{xy}(x, y) \) is the mixed partial derivative, first with respect to \( x \) and then \( y \).

To solve, you must apply rules for differentiation, treating other variables as constants during each step accordingly.
