integral of ((x+8)/(sqrt(x)))

\int (\frac{x + 8}{x}) d x

\frac{2}{3} x^{\frac{3}{2}} + 16 x + C

Solution steps

\int \frac{x + 8}{x} d x

Expand

\frac{x + 8}{x} : x + \frac{8}{x}

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

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

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

= \frac{2}{3} x^{\frac{3}{2}} + 16 x

Add a constant to the solution

= \frac{2}{3} x^{\frac{3}{2}} + 16 x + C

\int_{- 3}^{3} (15 - x^{2}) - (x^{2} - 3) d x

\int \frac{- 4}{cos ( x ) - 1} d x

6 (ln (y)) y^{^{'}} - x^{3} y = 0

x \to \frac{π}{2} lim (9 sec (x))

x \to \infty lim (\frac{1}{x} - 2)
