求$$$\int 24 x^{43} e^{2}\, dx$$$。
解答
套用常數倍法則 $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$,使用 $$$c=24 e^{2}$$$ 與 $$$f{\left(x \right)} = x^{43}$$$:
$${\color{red}{\int{24 x^{43} e^{2} d x}}} = {\color{red}{\left(24 e^{2} \int{x^{43} d x}\right)}}$$
套用冪次法則 $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$,以 $$$n=43$$$:
$$24 e^{2} {\color{red}{\int{x^{43} d x}}}=24 e^{2} {\color{red}{\frac{x^{1 + 43}}{1 + 43}}}=24 e^{2} {\color{red}{\left(\frac{x^{44}}{44}\right)}}$$
因此,
$$\int{24 x^{43} e^{2} d x} = \frac{6 x^{44} e^{2}}{11}$$
加上積分常數:
$$\int{24 x^{43} e^{2} d x} = \frac{6 x^{44} e^{2}}{11}+C$$
答案
$$$\int 24 x^{43} e^{2}\, dx = \frac{6 x^{44} e^{2}}{11} + C$$$A
