integral of (\sqrt[3]{x}-4+5x)/(x^2)

- \frac{3}{2 x ^{\frac{2}{3}}} + \frac{4}{x} + 5 ln ∣ x ∣ + C

Solution steps

Expand

= \int \frac{1}{x ^{\frac{5}{3}}} - \frac{4}{x ^{2}} + \frac{5}{x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{x ^{\frac{5}{3}}} d x - \int \frac{4}{x ^{2}} d x + \int \frac{5}{x} d x

\int \frac{1}{x ^{\frac{5}{3}}} d x = - \frac{3}{2 x ^{\frac{2}{3}}}

\int \frac{4}{x ^{2}} d x = - \frac{4}{x}

\int \frac{5}{x} d x = 5 ln ∣ x ∣

= - \frac{3}{2 x ^{\frac{2}{3}}} - (- \frac{4}{x}) + 5 ln ∣ x ∣

Simplify

= - \frac{3}{2 x ^{\frac{2}{3}}} + \frac{4}{x} + 5 ln ∣ x ∣

Add a constant to the solution

= - \frac{3}{2 x ^{\frac{2}{3}}} + \frac{4}{x} + 5 ln ∣ x ∣ + C

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

\int \frac{2 x ^{2}}{4 - x ^{2}} d x

\int x^{3} cos (8 x) d x

\int \frac{1 - sin ( x )}{2 + cos ( x )} d x

\int x^{5} ln (x^{3} + 1) d x
