Integral of $$$\frac{i d n t}{x^{115}}$$$ with respect to $$$x$$$

Find $$$\int \frac{i d n t}{x^{115}}\, dx$$$.

Apply the constant multiple rule $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ with $$$c=i d n t$$$ and $$$f{\left(x \right)} = \frac{1}{x^{115}}$$$:

$${\color{red}{\int{\frac{i d n t}{x^{115}} d x}}} = {\color{red}{i d n t \int{\frac{1}{x^{115}} d x}}}$$

Apply the power rule $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ with $$$n=-115$$$:

$$i d n t {\color{red}{\int{\frac{1}{x^{115}} d x}}}=i d n t {\color{red}{\int{x^{-115} d x}}}=i d n t {\color{red}{\frac{x^{-115 + 1}}{-115 + 1}}}=i d n t {\color{red}{\left(- \frac{x^{-114}}{114}\right)}}=i d n t {\color{red}{\left(- \frac{1}{114 x^{114}}\right)}}$$

Therefore,

$$\int{\frac{i d n t}{x^{115}} d x} = - \frac{i d n t}{114 x^{114}}$$

Add the constant of integration:

$$\int{\frac{i d n t}{x^{115}} d x} = - \frac{i d n t}{114 x^{114}}+C$$

$$$\int \frac{i d n t}{x^{115}}\, dx = - \frac{i d n t}{114 x^{114}} + C$$$A
