integral of x\sqrt[9]{4+x^2}

\frac{9}{20} (4 + x^{2})^{\frac{10}{9}} + C

Solution steps

Apply u-substitution

Take the constant out:

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

Apply the Power Rule

: \frac{9}{10} u^{\frac{10}{9}}

= \frac{1}{2} \cdot \frac{9}{10} u^{\frac{10}{9}}

Substitute back

u = 4 + x^{2}

= \frac{1}{2} \cdot \frac{9}{10} (4 + x^{2})^{\frac{10}{9}}

Simplify

\frac{1}{2} \cdot \frac{9}{10} (4 + x^{2})^{\frac{10}{9}} : \frac{9}{20} (4 + x^{2})^{\frac{10}{9}}

= \frac{9}{20} (4 + x^{2})^{\frac{10}{9}}

Add a constant to the solution

= \frac{9}{20} (4 + x^{2})^{\frac{10}{9}} + C

\frac{9 s}{9 s ^{2} + 1}

\frac{e ^{- s}}{s ^{5}}

x \to 0 lim (\frac{( 4 ^{x} - 1 )}{x})

\int sin (7 x - 10) d x

x \to \infty lim (4 x^{3})
