(\partial)/(\partial x)(x^2ln(xy))

\frac{\partial}{\partial x} (x^{2} ln (x y))

2 x ln (x y) + x

Solution steps

\frac{\partial}{\partial x} (x^{2} ln (x y))

Treat

y

as a constant

Apply the Product Rule:

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

f = x^{2}, g = ln (x y)

= \frac{\partial}{\partial x} (x^{2}) ln (x y) + \frac{\partial}{\partial x} (ln (x y)) x^{2}

\frac{\partial}{\partial x} (x^{2}) = 2 x

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

= 2 x ln (x y) + \frac{1}{x} x^{2}

\frac{1}{x} x^{2} = x

= 2 x ln (x y) + x
