integral of 3x^3

Solution

integral

3 x^{3}

Solution

\frac{3 x ^{4}}{4} + C

Solution steps

\int 3 x^{3} d x

Take the constant out:

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

= 3 \cdot \int x^{3} d x

Apply the Power Rule

= 3 \cdot \frac{x ^{4}}{4}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{3 x ^{4}}{4}

Add a constant to the solution

= \frac{3 x ^{4}}{4} + C
