\frac{d}{d x} (x ln (x^{18}))

18 ln (x) + 18

Solution steps

\frac{d}{d x} (x ln (x^{18}))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = ln (x^{18})

= \frac{d x}{d x} ln (x^{18}) + \frac{d}{d x} (ln (x^{18})) x

\frac{d x}{d x} = 1

\frac{d}{d x} (ln (x^{18})) = \frac{18}{x}

= 1 \cdot ln (x^{18}) + \frac{18}{x} x

Simplify

1 \cdot ln (x^{18}) + \frac{18}{x} x : 18 ln (x) + 18

= 18 ln (x) + 18

\int \frac{x ^{2} + 3 x - 1}{x + 2} d x

\int_{0}^{3} (8 - 2 x) d x

\frac{\partial}{\partial y} (sin (x y) + x sin (y))

f (x) = \frac{6}{x ^{4}}

\int e^{- \frac{3}{2} x} d x
