Integral de $$$\frac{13}{x^{\frac{28}{5}}}$$$

Encontre $$$\int \frac{13}{x^{\frac{28}{5}}}\, dx$$$.

Aplique a regra do múltiplo constante $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ usando $$$c=13$$$ e $$$f{\left(x \right)} = \frac{1}{x^{\frac{28}{5}}}$$$:

$${\color{red}{\int{\frac{13}{x^{\frac{28}{5}}} d x}}} = {\color{red}{\left(13 \int{\frac{1}{x^{\frac{28}{5}}} d x}\right)}}$$

Aplique a regra da potência $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ com $$$n=- \frac{28}{5}$$$:

$$13 {\color{red}{\int{\frac{1}{x^{\frac{28}{5}}} d x}}}=13 {\color{red}{\int{x^{- \frac{28}{5}} d x}}}=13 {\color{red}{\frac{x^{- \frac{28}{5} + 1}}{- \frac{28}{5} + 1}}}=13 {\color{red}{\left(- \frac{5 x^{- \frac{23}{5}}}{23}\right)}}=13 {\color{red}{\left(- \frac{5}{23 x^{\frac{23}{5}}}\right)}}$$

Portanto,

$$\int{\frac{13}{x^{\frac{28}{5}}} d x} = - \frac{65}{23 x^{\frac{23}{5}}}$$

Adicione a constante de integração:

$$\int{\frac{13}{x^{\frac{28}{5}}} d x} = - \frac{65}{23 x^{\frac{23}{5}}}+C$$

$$$\int \frac{13}{x^{\frac{28}{5}}}\, dx = - \frac{65}{23 x^{\frac{23}{5}}} + C$$$A
