(\partial)/(\partial y)(xye^{xy})

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

x (e^{x y} + e^{x y} x y)

Solution steps

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

Treat

x

as a constant

Take the constant out:

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

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = y, g = e^{x y}

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

\frac{\partial}{\partial y} (y) = 1

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

= x (1 \cdot e^{x y} + e^{x y} x y)

Simplify

= x (e^{x y} + e^{x y} x y)
