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

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

\frac{2 x}{x ^{2} + 3 y}

Solution steps

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

Treat

y

as a constant

Apply the chain rule:

\frac{1}{x ^{2} + 3 y} \frac{\partial}{\partial x} (x^{2} + 3 y)

= \frac{1}{x ^{2} + 3 y} \frac{\partial}{\partial x} (x^{2} + 3 y)

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

= \frac{1}{x ^{2} + 3 y} \cdot 2 x

Simplify

\frac{1}{x ^{2} + 3 y} \cdot 2 x : \frac{2 x}{x ^{2} + 3 y}

= \frac{2 x}{x ^{2} + 3 y}
