integral of 3x^{4/3}

\int 3 x^{\frac{4}{3}} d x

\frac{9}{7} x^{\frac{7}{3}} + C

Solution steps

\int 3 x^{\frac{4}{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^{\frac{4}{3}} d x

Apply the Power Rule

= 3 \cdot \frac{3}{7} x^{\frac{7}{3}}

Simplify

3 \cdot \frac{3}{7} x^{\frac{7}{3}} : \frac{9}{7} x^{\frac{7}{3}}

= \frac{9}{7} x^{\frac{7}{3}}

Add a constant to the solution

= \frac{9}{7} x^{\frac{7}{3}} + C

\int x + \frac{2}{x} d x

\int 3 e^{x} + 4 d x

\int (2 x + 1) \cdot cos (4 x) d x

\int \frac{5 x ^{2} + 14 x + 10}{( x + 2 ) ( x + 1 ) ^{2}} d x

\int sin (αx) d x
