integral of (sqrt(4+\sqrt{x)})/(sqrt(x))

\int \frac{4 + x}{x} d x

\frac{4}{3} (4 + x)^{\frac{3}{2}} + C

Solution steps

\int \frac{4 + x}{x} d x

Apply u-substitution

= \int 2 u d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int u d u

Apply the Power Rule

= 2 \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 4 + x

= 2 \cdot \frac{2}{3} (4 + x)^{\frac{3}{2}}

Simplify

2 \cdot \frac{2}{3} (4 + x)^{\frac{3}{2}} : \frac{4}{3} (4 + x)^{\frac{3}{2}}

= \frac{4}{3} (4 + x)^{\frac{3}{2}}

Add a constant to the solution

= \frac{4}{3} (4 + x)^{\frac{3}{2}} + C
