Find the derivative of the following functions (it is to be understand that a,b,c,d,p,q,r and s are fixed non-zero constants and m and n are integers):
`(px+q)((r)/(x)+s)`

Explanation

To find the derivative of the function \( y = (px + q)\left(\frac{r}{x} + s\right) \), we will follow these steps:

### Step 1: Expand the function
First, we will expand the expression to make differentiation easier.

\[ y = (px + q)\left(\frac{r}{x} + s\right) \]
