integral of 2sqrt(u)

\int 2 u d u

\frac{4}{3} u^{\frac{3}{2}} + C

Solution steps

\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}}

Simplify

2 \cdot \frac{2}{3} u^{\frac{3}{2}} : \frac{4}{3} u^{\frac{3}{2}}

= \frac{4}{3} u^{\frac{3}{2}}

Add a constant to the solution

= \frac{4}{3} u^{\frac{3}{2}} + C
