integral of (3x^4)/(sqrt(1-9x^5))

\int \frac{3 x ^{4}}{1 - 9 x ^{5}} d x

- \frac{2}{15} 1 - 9 x^{5} + C

Solution steps

\int \frac{3 x ^{4}}{1 - 9 x ^{5}} d x

Take the constant out:

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

= 3 \cdot \int \frac{x ^{4}}{1 - 9 x ^{5}} d x

Apply u-substitution

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

Take the constant out:

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

= 3 (- \frac{1}{45} \cdot \int \frac{1}{u} d u)

Apply the Power Rule

= 3 (- \frac{1}{45} \cdot 2 u^{\frac{1}{2}})

Substitute back

u = 1 - 9 x^{5}

= 3 (- \frac{1}{45} \cdot 2 (1 - 9 x^{5})^{\frac{1}{2}})

Simplify

3 (- \frac{1}{45} \cdot 2 (1 - 9 x^{5})^{\frac{1}{2}}) : - \frac{2}{15} 1 - 9 x^{5}

= - \frac{2}{15} 1 - 9 x^{5}

Add a constant to the solution

= - \frac{2}{15} 1 - 9 x^{5} + C
