**Problem 1**

Suppose \( W(x, y, z) = 20z \ln y - 13x^7y^3 + 5xz^2 \).

Tasks:

(a) Find \(\frac{\partial W}{\partial x}\)

(b) Find \(\frac{\partial W}{\partial y}\)

(c) Find \(\frac{\partial W}{\partial z}\)

(d) Find \(\frac{\partial^2 W}{\partial x^2}\)

---

The problem asks to find partial derivatives of the function \( W \) with respect to variables \( x \), \( y \), and \( z \), as well as the second partial derivative with respect to \( x \). Each task requires applying the rules of differentiation while treating other variables as constants.
