integral of (x^3)/(sqrt(u))

\int \frac{x ^{3}}{u} d x

\frac{x ^{4}}{4 u} + C

Solution steps

\int \frac{x ^{3}}{u} d x

Take the constant out:

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

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

Apply the Power Rule

= \frac{1}{u} \cdot \frac{x ^{4}}{4}

Simplify

\frac{1}{u} \cdot \frac{x ^{4}}{4} : \frac{x ^{4}}{4 u}

= \frac{x ^{4}}{4 u}

Add a constant to the solution

= \frac{x ^{4}}{4 u} + C
