integral of (x^2sqrt(x^3+5))

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

\frac{2}{9} (x^{3} + 5)^{\frac{3}{2}} + C

Solution steps

\int x^{2} x^{3} + 5 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} + 5

= \frac{1}{3} \cdot \frac{2}{3} (x^{3} + 5)^{\frac{3}{2}}

Simplify

\frac{1}{3} \cdot \frac{2}{3} (x^{3} + 5)^{\frac{3}{2}} : \frac{2}{9} (x^{3} + 5)^{\frac{3}{2}}

= \frac{2}{9} (x^{3} + 5)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{9} (x^{3} + 5)^{\frac{3}{2}} + C

(3, 4), (8, - 3)

x \to 3 lim (2 x^{2} + x - 7)

\int x^{2} - 36 d x

ln (\frac{1 - sin ( x )}{1 + sin ( x )})

\frac{d}{d x} (5^{2})
