\frac{d}{d x} (ln (7 x^{3}))

\frac{3}{x}

Solution steps

\frac{d}{d x} (ln (7 x^{3}))

Apply the chain rule:

\frac{1}{7 x ^{3}} \frac{d}{d x} (7 x^{3})

= \frac{1}{7 x ^{3}} \frac{d}{d x} (7 x^{3})

\frac{d}{d x} (7 x^{3}) = 21 x^{2}

= \frac{1}{7 x ^{3}} \cdot 21 x^{2}

Simplify

\frac{1}{7 x ^{3}} \cdot 21 x^{2} : \frac{3}{x}

= \frac{3}{x}

(x^{2} + y + y^{2}) d x = x d y

y = x + x

2 x^{π}

\int (2 x + 5)^{10} d x
