(\partial)/(\partial y)(7ze^{xyz})

\frac{\partial}{\partial y} (7 z e^{x yz})

7 e^{z x y} z^{2} x

Solution steps

\frac{\partial}{\partial y} (7 z e^{x yz})

Treat

z, x

as constants

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 7 z \frac{\partial}{\partial y} (e^{x yz})

Apply the chain rule:

e^{x yz} \frac{\partial}{\partial y} (x yz)

= e^{x yz} \frac{\partial}{\partial y} (x yz)

\frac{\partial}{\partial y} (x yz) = z x

= 7 z e^{x yz} z x

Simplify

7 z e^{x yz} z x : 7 e^{z x y} z^{2} x

= 7 e^{z x y} z^{2} x
