integral of (x^{3/2}+8)^5sqrt(x)

\int (x^{\frac{3}{2}} + 8)^{5} x d x

\frac{1}{9} (x^{\frac{3}{2}} + 8)^{6} + C

Solution steps

\int (x^{\frac{3}{2}} + 8)^{5} x d x

Apply u-substitution

= \int \frac{2 u ^{5}}{3} d u

Take the constant out:

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

= \frac{2}{3} \cdot \int u^{5} d u

Apply the Power Rule

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

Substitute back

u = x^{\frac{3}{2}} + 8

= \frac{2}{3} \cdot \frac{( x ^{\frac{3}{2}} + 8 ) ^{6}}{6}

Simplify

\frac{2}{3} \cdot \frac{( x ^{\frac{3}{2}} + 8 ) ^{6}}{6} : \frac{1}{9} (x^{\frac{3}{2}} + 8)^{6}

= \frac{1}{9} (x^{\frac{3}{2}} + 8)^{6}

Add a constant to the solution

= \frac{1}{9} (x^{\frac{3}{2}} + 8)^{6} + C
