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

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

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

Solution steps

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

Expand

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

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

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

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

Add a constant to the solution

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

\int cos (x) tan (sin (x)) d x

\int - 7 x^{3} e^{x^{2}} d x

\int \frac{1}{4 x ^{2} + 4 x + 1} d x

\int \frac{x ^{2} - 4 x - 3}{3 x ^{3} + 17 x ^{2} - 6 x} d x

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