(\partial)/(\partial x)(ln(4x^2))

\frac{\partial}{\partial x} (ln (4 x^{2}))

\frac{2}{x}

Solution steps

\frac{\partial}{\partial x} (ln (4 x^{2}))

Apply the chain rule:

\frac{1}{4 x ^{2}} \frac{\partial}{\partial x} (4 x^{2})

= \frac{1}{4 x ^{2}} \frac{\partial}{\partial x} (4 x^{2})

\frac{\partial}{\partial x} (4 x^{2}) = 8 x

= \frac{1}{4 x ^{2}} \cdot 8 x

Simplify

\frac{1}{4 x ^{2}} \cdot 8 x : \frac{2}{x}

= \frac{2}{x}
