integral of (3x^2)^2

Solution

\int (3 x^{2})^{2} d x

Solution

\frac{9 x ^{5}}{5} + C

Solution steps

\int (3 x^{2})^{2} d x

Simplify

(3 x^{2})^{2} : 9 x^{4}

= \int 9 x^{4} d x

Take the constant out:

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

= 9 \cdot \int x^{4} d x

Apply the Power Rule

= 9 \cdot \frac{x ^{5}}{5}

Multiply fractions:

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

= \frac{9 x ^{5}}{5}

Add a constant to the solution

= \frac{9 x ^{5}}{5} + C
