Apply the power rule for integration, $\displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}$, where $n$ represents a number or constant function, such as $-\frac{8}{9}$

Divide fractions $\frac{\sqrt[9]{v}}{\frac{1}{9}}$ with Keep, Change, Flip: $a\div \frac{b}{c}=\frac{a}{1}\div\frac{b}{c}=\frac{a}{1}\times\frac{c}{b}=\frac{a\cdot c}{b}$

As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$
