Answer:
Step-by-step explanation:
The given function is
We need to find first partial derivatives of the function.
Differentiate partially w.r.t. x and y, z are constants.
Differentiate partially w.r.t. y and x, z are constants.
Differentiate partially w.r.t. z and x, y are constants.
Therefore, the first partial derivatives of the function are .
