integral of (9/(sqrt(x))+9sqrt(x))

\int (\frac{9}{x} + 9 x) d x

18 x + 6 x^{\frac{3}{2}} + C

Solution steps

\int \frac{9}{x} + 9 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{9}{x} d x + \int 9 x d x

\int \frac{9}{x} d x = 18 x

\int 9 x d x = 6 x^{\frac{3}{2}}

= 18 x + 6 x^{\frac{3}{2}}

Add a constant to the solution

= 18 x + 6 x^{\frac{3}{2}} + C
