Evaluate

$$\int ndn$$

$$\text{Use the property of integral }\int x^{n}dx=\frac{x^{n+1}}{n+1}$$

$$\frac{n^{1+1}}{1+1}$$

Add the numbers

$$\frac{n^2}{1+1}$$

Add the numbers

$$\frac{n^2}{2}$$

$$\text{Add the constant of integral }{C}_2$$

$$\frac{n^2}{2}+C_2,C_2\in \mathbb{R}$$

$$i+C_1=\frac{n^2}{2}+C_2,C_1\in \mathbb{R},C_2\in \mathbb{R}$$
