integral of 6^3+3/x+1/(x^2)

\int 6^{3} + \frac{3}{x} + \frac{1}{x ^{2}} d x

216 x + 3 ln ∣ x ∣ - \frac{1}{x} + C

Solution steps

\int 6^{3} + \frac{3}{x} + \frac{1}{x ^{2}} d x

Simplify

= \int 216 + \frac{3}{x} + \frac{1}{x ^{2}} 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 216 d x + \int \frac{3}{x} d x + \int \frac{1}{x ^{2}} d x

\int 216 d x = 216 x

\int \frac{3}{x} d x = 3 ln ∣ x ∣

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

= 216 x + 3 ln ∣ x ∣ - \frac{1}{x}

Add a constant to the solution

= 216 x + 3 ln ∣ x ∣ - \frac{1}{x} + C
