(\partial)/(\partial x)(4e^{xy})

\frac{\partial}{\partial x} (4 e^{x y})

4 e^{x y} y

Solution steps

\frac{\partial}{\partial x} (4 e^{x y})

Treat

y

as a constant

Take the constant out:

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

= 4 \frac{\partial}{\partial x} (e^{x y})

Apply the chain rule:

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

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

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

= 4 e^{x y} y
