integral of sqrt(9+x)

\int 9 + x d x

\frac{2}{3} (9 + x)^{\frac{3}{2}} + C

Solution steps

\int 9 + x d x

Apply u-substitution

= \int u d u

Apply the Power Rule

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

Substitute back

u = 9 + x

= \frac{2}{3} (9 + x)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{3} (9 + x)^{\frac{3}{2}} + C
