Integral dari $$$81 x^{16}$$$

Temukan $$$\int 81 x^{16}\, dx$$$.

Terapkan aturan pengali konstanta $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ dengan $$$c=81$$$ dan $$$f{\left(x \right)} = x^{16}$$$:

$${\color{red}{\int{81 x^{16} d x}}} = {\color{red}{\left(81 \int{x^{16} d x}\right)}}$$

Terapkan aturan pangkat $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ dengan $$$n=16$$$:

$$81 {\color{red}{\int{x^{16} d x}}}=81 {\color{red}{\frac{x^{1 + 16}}{1 + 16}}}=81 {\color{red}{\left(\frac{x^{17}}{17}\right)}}$$

Oleh karena itu,

$$\int{81 x^{16} d x} = \frac{81 x^{17}}{17}$$

Tambahkan konstanta integrasi:

$$\int{81 x^{16} d x} = \frac{81 x^{17}}{17}+C$$

$$$\int 81 x^{16}\, dx = \frac{81 x^{17}}{17} + C$$$A
