(\partial)/(\partial y)(ln(3xy)+x^2)

\frac{\partial}{\partial y} (ln (3 x y) + x^{2})

\frac{1}{y}

Solution steps

\frac{\partial}{\partial y} (ln (3 x y) + x^{2})

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (ln (3 x y)) + \frac{\partial}{\partial y} (x^{2})

\frac{\partial}{\partial y} (ln (3 x y)) = \frac{1}{y}

\frac{\partial}{\partial y} (x^{2}) = 0

= \frac{1}{y} + 0

Simplify

= \frac{1}{y}
