integral of \sqrt[3]{2x-1}

\int 3 2 x - 1 d x

\frac{3}{8} (2 x - 1)^{\frac{4}{3}} + C

Solution steps

\int 3 2 x - 1 d x

Apply u-substitution

: \int \frac{3 u}{2} d u

= \int \frac{3 u}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int 3 u d u

Apply the Power Rule

: \frac{3}{4} u^{\frac{4}{3}}

= \frac{1}{2} \cdot \frac{3}{4} u^{\frac{4}{3}}

Substitute back

u = 2 x - 1

= \frac{1}{2} \cdot \frac{3}{4} (2 x - 1)^{\frac{4}{3}}

Simplify

\frac{1}{2} \cdot \frac{3}{4} (2 x - 1)^{\frac{4}{3}} : \frac{3}{8} (2 x - 1)^{\frac{4}{3}}

= \frac{3}{8} (2 x - 1)^{\frac{4}{3}}

Add a constant to the solution

= \frac{3}{8} (2 x - 1)^{\frac{4}{3}} + C

\int cos (x + 3) d x

\int cos (x + 1) d x

\int 2 x^{3} e^{- x^{4} + 12} d x

\int \frac{e ^{x}}{e ^{x} + 7} d x

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