integral of (x^2+3)/(\sqrt[3]{x+2)}

\frac{3}{8} (x + 2)^{\frac{8}{3}} - \frac{12}{5} (x + 2)^{\frac{5}{3}} + \frac{21}{2} (x + 2)^{\frac{2}{3}} + C

Solution steps

Apply u-substitution

Expand

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

\int u^{\frac{5}{3}} d u = \frac{3}{8} u^{\frac{8}{3}}

\int 4 u^{\frac{2}{3}} d u = \frac{12}{5} u^{\frac{5}{3}}

= \frac{3}{8} u^{\frac{8}{3}} - \frac{12}{5} u^{\frac{5}{3}} + \frac{21}{2} u^{\frac{2}{3}}

Substitute back

u = x + 2

= \frac{3}{8} (x + 2)^{\frac{8}{3}} - \frac{12}{5} (x + 2)^{\frac{5}{3}} + \frac{21}{2} (x + 2)^{\frac{2}{3}}

Add a constant to the solution

= \frac{3}{8} (x + 2)^{\frac{8}{3}} - \frac{12}{5} (x + 2)^{\frac{5}{3}} + \frac{21}{2} (x + 2)^{\frac{2}{3}} + C

\frac{\partial}{\partial x} (10 (11 x - 3 y + 12)^{5})

\frac{d}{d x} (x - \frac{3}{2})

\int csc^{2} (y) \frac{1}{1 + cot ( y )} d y

\frac{d}{d x} (\frac{x ^{2}}{y ^{3}})

x \to 2 lim (x^{2} + x + 2)
