integral of (7x^3-8sqrt(x))/x

\int \frac{7 x ^{3} - 8 x}{x} d x

\frac{7 x ^{3}}{3} - 16 x + C

Solution steps

\int \frac{7 x ^{3} - 8 x}{x} d x

Expand

\frac{7 x ^{3} - 8 x}{x} : 7 x^{2} - \frac{8}{x}

= \int 7 x^{2} - \frac{8}{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 7 x^{2} d x - \int \frac{8}{x} d x

\int 7 x^{2} d x = \frac{7 x ^{3}}{3}

\int \frac{8}{x} d x = 16 x

= \frac{7 x ^{3}}{3} - 16 x

Add a constant to the solution

= \frac{7 x ^{3}}{3} - 16 x + C

\int 8 x^{- 1} + 6 d x

\int csc^{4} (8 t) cot (8 t) d t

\int x^{2} \cdot csch (x^{3} + 1) d x

\int 4 θ d θ

\int (a^{x}) d x
