integral of sqrt(x)sqrt(x^{3/2)-1}

\int x x^{\frac{3}{2}} - 1 d x

\frac{4}{9} (x^{\frac{3}{2}} - 1)^{\frac{3}{2}} + C

Solution steps

\int x x^{\frac{3}{2}} - 1 d x

Apply u-substitution

= \int 2 u^{2} u^{3} - 1 d u

Take the constant out:

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

= 2 \cdot \int u^{2} u^{3} - 1 d u

Apply u-substitution

= 2 \cdot \int \frac{v}{3} d v

Take the constant out:

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

= 2 \cdot \frac{1}{3} \cdot \int v d v

Apply the Power Rule

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

Substitute back

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

Simplify

2 \cdot \frac{1}{3} \cdot \frac{2}{3} ((x)^{3} - 1)^{\frac{3}{2}} : \frac{4}{9} (x^{\frac{3}{2}} - 1)^{\frac{3}{2}}

= \frac{4}{9} (x^{\frac{3}{2}} - 1)^{\frac{3}{2}}

Add a constant to the solution

= \frac{4}{9} (x^{\frac{3}{2}} - 1)^{\frac{3}{2}} + C
