integral of x^2(x^3+9)^7

\int x^{2} (x^{3} + 9)^{7} d x

\frac{1}{24} (x^{3} + 9)^{8} + C

Solution steps

\int x^{2} (x^{3} + 9)^{7} d x

Apply u-substitution

: \int \frac{u ^{7}}{3} d u

= \int \frac{u ^{7}}{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^{7} d u

Apply the Power Rule

: \frac{u ^{8}}{8}

= \frac{1}{3} \cdot \frac{u ^{8}}{8}

Substitute back

u = x^{3} + 9

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

Simplify

\frac{1}{3} \cdot \frac{( x ^{3} + 9 ) ^{8}}{8} : \frac{1}{24} (x^{3} + 9)^{8}

= \frac{1}{24} (x^{3} + 9)^{8}

Add a constant to the solution

= \frac{1}{24} (x^{3} + 9)^{8} + C

f (x) = x^{\frac{7}{5}} (x + 5)

y^{^{'}} = (0.04 \cdot 4) - \frac{y}{1840} 4, y (0) = 0

\int sinh (14 x) d x

\int x^{- 1} sin (x) d x

x \to 0 lim (\frac{1 - cos ( 5 x )}{x})
