\frac{d}{d x} (5 ln (2 x))

\frac{5}{x}

Solution steps

\frac{d}{d x} (5 ln (2 x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 5 \frac{d}{d x} (ln (2 x))

Apply the chain rule:

\frac{1}{2 x} \frac{d}{d x} (2 x)

= \frac{1}{2 x} \frac{d}{d x} (2 x)

\frac{d}{d x} (2 x) = 2

= 5 \cdot \frac{1}{2 x} \cdot 2

Simplify

5 \cdot \frac{1}{2 x} \cdot 2 : \frac{5}{x}

= \frac{5}{x}

\int_{0}^{3 π} 7 x^{2} sin (\frac{1}{6} x) d x

y = \frac{x}{9} - \frac{9}{x}

\frac{d}{d x} (3 + 3 cos (x))

\int 15 x 1 - x d x

\int \frac{1}{( x ^{2} + 6 x + 13 )} d x
