Datrys x=sqrt{xy}

$$x = \sqrt { x y }$$

Datrys ar gyfer y

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

Camau ar gyfer Datrys Hafaliadau Radical

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

$$\sqrt{xy}=x$$

Sgwariwch ddwy ochr yr hafaliad.

$$xy=x^{2}$$

Rhannu’r ddwy ochr â x.

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

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

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

Rhannwch x^{2} â x.

$$y=x$$

Datrys ar gyfer x (complex solution)

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

Datrys ar gyfer y (complex solution)

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

Datrys ar gyfer x

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