integral of sqrt(x+7)

\int x + 7 d x

\frac{2}{3} (x + 7)^{\frac{3}{2}} + C

Solution steps

\int x + 7 d x

Apply u-substitution

: \int u d u

= \int u d u

Apply the Power Rule

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

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

Substitute back

u = x + 7

= \frac{2}{3} (x + 7)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{3} (x + 7)^{\frac{3}{2}} + C

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

\int 4 cos (x) + sec^{2} (x) d x

\int e^{- s x} \cdot cos (b x) d x

\int \frac{e ^{x}}{9 + e ^{2 x}} d x

\int 8 + 3 x^{2} d x
