$p x^{2} y$

Step 1

Since $p y$ is constant with respect to $x$ , the derivative of $p x^{2} y$ with respect to $x$ is $p y \frac{d}{d x} [x^{2}]$ .

$p y \frac{d}{d x} [x^{2}]$

Step 2

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 2$ .

$p y (2 x)$

Step 3

Reorder.

Step 3.1

Move $2$ to the left of $p y$ .

$2 \cdot (p y) x$

Step 3.2

Reorder the factors of $2 p y x$ .
