$$$x$$$에 대한 $$$\frac{\sqrt{x y}}{x^{2} y^{2}}$$$의 적분

$$$\int \frac{\sqrt{x y}}{x^{2} y^{2}}\, dx$$$을(를) 구하시오.

입력이 다음과 같이 다시 쓰입니다: $$$\int{\frac{\sqrt{x y}}{x^{2} y^{2}} d x}=\int{\frac{1}{x^{\frac{3}{2}} y^{\frac{3}{2}}} d x}$$$.

상수배 법칙 $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$을 $$$c=\frac{1}{y^{\frac{3}{2}}}$$$와 $$$f{\left(x \right)} = \frac{1}{x^{\frac{3}{2}}}$$$에 적용하세요:

$${\color{red}{\int{\frac{1}{x^{\frac{3}{2}} y^{\frac{3}{2}}} d x}}} = {\color{red}{\frac{\int{\frac{1}{x^{\frac{3}{2}}} d x}}{y^{\frac{3}{2}}}}}$$

멱법칙($$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$)을 $$$n=- \frac{3}{2}$$$에 적용합니다:

$$\frac{{\color{red}{\int{\frac{1}{x^{\frac{3}{2}}} d x}}}}{y^{\frac{3}{2}}}=\frac{{\color{red}{\int{x^{- \frac{3}{2}} d x}}}}{y^{\frac{3}{2}}}=\frac{{\color{red}{\frac{x^{- \frac{3}{2} + 1}}{- \frac{3}{2} + 1}}}}{y^{\frac{3}{2}}}=\frac{{\color{red}{\left(- 2 x^{- \frac{1}{2}}\right)}}}{y^{\frac{3}{2}}}=\frac{{\color{red}{\left(- \frac{2}{\sqrt{x}}\right)}}}{y^{\frac{3}{2}}}$$

따라서,

$$\int{\frac{1}{x^{\frac{3}{2}} y^{\frac{3}{2}}} d x} = - \frac{2}{\sqrt{x} y^{\frac{3}{2}}}$$

적분 상수를 추가하세요:

$$\int{\frac{1}{x^{\frac{3}{2}} y^{\frac{3}{2}}} d x} = - \frac{2}{\sqrt{x} y^{\frac{3}{2}}}+C$$

$$$\int \frac{\sqrt{x y}}{x^{2} y^{2}}\, dx = - \frac{2}{\sqrt{x} y^{\frac{3}{2}}} + C$$$A
