## Homework Statement

Find (∂z/∂x) of 6xyz

## Homework Equations

N/a

## The Attempt at a Solution

The correct answer is 6xy(∂z/∂x) but I would like proof of it. I got something different when I tried taking the partial derivative.

6xyz = 6x(yz) = Multiplication rule for derivatives

6(∂x/∂x) + y(∂z/∂x)

What did I do wrong? Thanks
