integral of 3x^8

Solution

\int 3 x^{8} d x

Solution

\frac{x ^{9}}{3} + C

Solution steps

\int 3 x^{8} d x

Take the constant out:

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

= 3 \cdot \int x^{8} d x

Apply the Power Rule

= 3 \cdot \frac{x ^{9}}{9}

Simplify

3 \cdot \frac{x ^{9}}{9} : \frac{x ^{9}}{3}

= \frac{x ^{9}}{3}

Add a constant to the solution

= \frac{x ^{9}}{3} + C
