integral of 4/5 x

Solution

\int \frac{4}{5} x d x

Solution

\frac{2 x ^{2}}{5} + C

Solution steps

\int \frac{4}{5} x d x

Take the constant out:

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

= \frac{4}{5} \cdot \int x d x

Apply the Power Rule

= \frac{4}{5} \cdot \frac{x ^{2}}{2}

Simplify

\frac{4}{5} \cdot \frac{x ^{2}}{2} : \frac{2 x ^{2}}{5}

= \frac{2 x ^{2}}{5}

Add a constant to the solution

= \frac{2 x ^{2}}{5} + C
