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

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

\frac{1}{60} (5 x^{3} + 2)^{4} + C

Solution steps

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

Apply u-substitution

: \int \frac{u ^{\frac{1}{3}}}{45} d u

= \int \frac{u ^{\frac{1}{3}}}{45} d u

Take the constant out:

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

= \frac{1}{45} \cdot \int u^{\frac{1}{3}} d u

Apply the Power Rule

: \frac{3}{4} u^{\frac{4}{3}}

= \frac{1}{45} \cdot \frac{3}{4} u^{\frac{4}{3}}

Substitute back

u = (5 x^{3} + 2)^{3}

= \frac{1}{45} \cdot \frac{3}{4} ((5 x^{3} + 2)^{3})^{\frac{4}{3}}

Simplify

\frac{1}{45} \cdot \frac{3}{4} ((5 x^{3} + 2)^{3})^{\frac{4}{3}} : \frac{1}{60} (5 x^{3} + 2)^{4}

= \frac{1}{60} (5 x^{3} + 2)^{4}

Add a constant to the solution

= \frac{1}{60} (5 x^{3} + 2)^{4} + C

\int \frac{3}{x ^{2} - 5 x + 6} d x

\int \frac{- sin ( 2 x )}{cos ( 2 x )} d x

\int \frac{7}{9 + 7 x} d x

\int x (15 - x)^{\frac{1}{2}} d x

\int \frac{( 8 ln ( x ) - 4 ) ^{6}}{x} d x
