integral of x^2sqrt(11+x^3)

\int x^{2} 11 + x^{3} d x

\frac{2}{9} (11 + x^{3})^{\frac{3}{2}} + C

Solution steps

\int x^{2} 11 + x^{3} 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 = 11 + x^{3}

= \frac{1}{3} \cdot \frac{2}{3} (11 + x^{3})^{\frac{3}{2}}

Simplify

\frac{1}{3} \cdot \frac{2}{3} (11 + x^{3})^{\frac{3}{2}} : \frac{2}{9} (11 + x^{3})^{\frac{3}{2}}

= \frac{2}{9} (11 + x^{3})^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{9} (11 + x^{3})^{\frac{3}{2}} + C

f (x) = tan (3 x)

\frac{d}{d x} (- 0.9 x^{2} + 1.7 x + 2.5)

\int x^{3} arcsin (\frac{1}{x}) d x

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

f (x) = 8 x^{9} - 3 x^{6} + 12 x^{3}
