integral of x^2sqrt(x^3+2)

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

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

Solution steps

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

Apply u-substitution

: \int \frac{u}{3} d u

= \int \frac{u}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int u d u

Apply the Power Rule

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

= \frac{1}{3} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = x^{3} + 2

= \frac{1}{3} \cdot \frac{2}{3} (x^{3} + 2)^{\frac{3}{2}}

Simplify

\frac{1}{3} \cdot \frac{2}{3} (x^{3} + 2)^{\frac{3}{2}} : \frac{2}{9} (x^{3} + 2)^{\frac{3}{2}}

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

Add a constant to the solution

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

n = 0 \sum \infty \frac{1}{4 ^{n + 1}}

\frac{d}{d x} (e^{x^{2} - 2 x + 1})

\frac{\partial}{\partial x} (x^{3} y^{2} e^{x z})

\frac{d}{d x} (\frac{1 + e ^{- 2 x}}{2 + cos ( 2 x )})

\int (cos (\frac{x}{2}))^{2} d x
