(\partial)/(\partial x)(3+xln(xy-5))

\frac{\partial}{\partial x} (3 + x ln (x y - 5))

\frac{x y}{x y - 5} + ln (x y - 5)

Solution steps

\frac{\partial}{\partial x} (3 + x ln (x y - 5))

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

= \frac{\partial}{\partial x} (3) + \frac{\partial}{\partial x} (x ln (x y - 5))

\frac{\partial}{\partial x} (3) = 0

\frac{\partial}{\partial x} (x ln (x y - 5)) = ln (y x - 5) + \frac{y x}{y x - 5}

= 0 + ln (y x - 5) + \frac{y x}{y x - 5}

Simplify

= \frac{x y}{x y - 5} + ln (x y - 5)
