Your Input
Find $$$\int r^{5}\, dr$$$.
Solution
Apply the power rule $$$\int r^{n}\, dr = \frac{r^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ with $$$n=5$$$:
$${\color{red}{\int{r^{5} d r}}}={\color{red}{\frac{r^{1 + 5}}{1 + 5}}}={\color{red}{\left(\frac{r^{6}}{6}\right)}}$$
Therefore,
$$\int{r^{5} d r} = \frac{r^{6}}{6}$$
Add the constant of integration:
$$\int{r^{5} d r} = \frac{r^{6}}{6}+C$$
Answer
$$$\int r^{5}\, dr = \frac{r^{6}}{6} + C$$$A
