integral of 4x^{2/3}

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

\frac{12}{5} x^{\frac{5}{3}} + C

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule

: \frac{3}{5} x^{\frac{5}{3}}

= 4 \cdot \frac{3}{5} x^{\frac{5}{3}}

Simplify

4 \cdot \frac{3}{5} x^{\frac{5}{3}} : \frac{12}{5} x^{\frac{5}{3}}

= \frac{12}{5} x^{\frac{5}{3}}

Add a constant to the solution

= \frac{12}{5} x^{\frac{5}{3}} + C

\frac{\partial}{\partial y} (3 x + 2 x y^{2})

\int \frac{4}{( x ^{2} + 5 x - 14 )} d x

x \to 2 lim (2 x^{2} - 3)

x \to - 1 + lim (\frac{1}{x ^{2} - 1})

\int \frac{2 x ^{3} + x ^{2} - 21 x + 24}{x ^{2} + 2 x - 8} d x
