Integral de $$$3 x^{\pi}$$$

Encontre $$$\int 3 x^{\pi}\, dx$$$.

Aplique a regra do múltiplo constante $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ usando $$$c=3$$$ e $$$f{\left(x \right)} = x^{\pi}$$$:

$${\color{red}{\int{3 x^{\pi} d x}}} = {\color{red}{\left(3 \int{x^{\pi} d x}\right)}}$$

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

$$3 {\color{red}{\int{x^{\pi} d x}}}=3 {\color{red}{\frac{x^{1 + \pi}}{1 + \pi}}}=3 {\color{red}{\frac{x^{1 + \pi}}{1 + \pi}}}$$

Portanto,

$$\int{3 x^{\pi} d x} = \frac{3 x^{1 + \pi}}{1 + \pi}$$

Adicione a constante de integração:

$$\int{3 x^{\pi} d x} = \frac{3 x^{1 + \pi}}{1 + \pi}+C$$

$$$\int 3 x^{\pi}\, dx = \frac{3 x^{1 + \pi}}{1 + \pi} + C$$$A
