integral of 2x^{3/4}

\int 2 x^{\frac{3}{4}} d x

\frac{8}{7} x^{\frac{7}{4}} + C

Solution steps

\int 2 x^{\frac{3}{4}} d x

Take the constant out:

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

= 2 \cdot \int x^{\frac{3}{4}} d x

Apply the Power Rule

= 2 \cdot \frac{4}{7} x^{\frac{7}{4}}

Simplify

2 \cdot \frac{4}{7} x^{\frac{7}{4}} : \frac{8}{7} x^{\frac{7}{4}}

= \frac{8}{7} x^{\frac{7}{4}}

Add a constant to the solution

= \frac{8}{7} x^{\frac{7}{4}} + C

\int \frac{2 - 3 x}{2 + 3 x} d x

\int \frac{x ^{3} + 4 x - 1}{x ^{2} + 5} d x

\int x sin (x) cos (n x) d x

\int \frac{1}{3 - cos ( x )} d x

\int 3 (8 y - 1) e^{4 y^{2} - y} d y
