integral of 4x^3

Solution

\int 4 x^{3} d x

Solution

x^{4} + C

Solution steps

\int 4 x^{3} d x

Take the constant out:

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

= 4 \cdot \int x^{3} d x

Apply the Power Rule

: \frac{x ^{4}}{4}

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

Simplify

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

= x^{4}

Add a constant to the solution

= x^{4} + C
