integral of x^5sqrt(12+x^6)

\int x^{5} 12 + x^{6} d x

\frac{1}{9} (12 + x^{6})^{\frac{3}{2}} + C

Solution steps

\int x^{5} 12 + x^{6} d x

Apply u-substitution

: \int \frac{u}{6} d u

= \int \frac{u}{6} d u

Take the constant out:

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

= \frac{1}{6} \cdot \int u d u

Apply the Power Rule

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

= \frac{1}{6} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 12 + x^{6}

= \frac{1}{6} \cdot \frac{2}{3} (12 + x^{6})^{\frac{3}{2}}

Simplify

\frac{1}{6} \cdot \frac{2}{3} (12 + x^{6})^{\frac{3}{2}} : \frac{1}{9} (12 + x^{6})^{\frac{3}{2}}

= \frac{1}{9} (12 + x^{6})^{\frac{3}{2}}

Add a constant to the solution

= \frac{1}{9} (12 + x^{6})^{\frac{3}{2}} + C

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

\int \frac{4 x}{2 x + 1} d x

\int x^{9} d x

y = x + e^{2 x}

x^{3}, x, - 1, 1
