Datrys y=sqrt{xy}

$$y= \sqrt{ xy }$$

Datrys ar gyfer x

$$\left\{\begin{matrix}x=y\text{, }&y\geq 0\\x\in \mathrm{R}\text{, }&y=0\end{matrix}\right.$$

Camau ar gyfer Datrys Hafaliadau Radical

Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$\sqrt{xy}=y$$

Sgwariwch ddwy ochr yr hafaliad.

$$yx=y^{2}$$

Rhannu’r ddwy ochr â y.

$$\frac{yx}{y}=\frac{y^{2}}{y}$$

Mae rhannu â y yn dad-wneud lluosi â y.

$$x=\frac{y^{2}}{y}$$

Rhannwch y^{2} â y.

$$x=y$$

Datrys ar gyfer x (complex solution)

$$\left\{\begin{matrix}x=y\text{, }&arg(y)<\pi \text{ or }y=0\\x\in \mathrm{C}\text{, }&y=0\end{matrix}\right.$$

Datrys ar gyfer y (complex solution)

$$\left\{\begin{matrix}\\y=0\text{, }&\text{unconditionally}\\y=x\text{, }&arg(x)<\pi \text{ or }x=0\end{matrix}\right.$$

Datrys ar gyfer y

$$\left\{\begin{matrix}\\y=0\text{, }&\text{unconditionally}\\y=x\text{, }&x\geq 0\end{matrix}\right.$$
