sqrt{x^4}sqrt{y}=x eching

$$\sqrt { x ^ { 4 } } \sqrt { y } = x$$

y uchun yechish

$$\left\{\begin{matrix}y=\frac{1}{x^{2}}\text{, }&x>0\\y\geq 0\text{, }&x=0\end{matrix}\right,$$

Ildizli tenglamalarni yechish qadamlari

Ikki tarafini \sqrt{x^{4}} ga bo‘ling.

$$\frac{\sqrt{x^{4}}\sqrt{y}}{\sqrt{x^{4}}}=\frac{x}{\sqrt{x^{4}}}$$

\sqrt{x^{4}} ga bo'lish \sqrt{x^{4}} ga ko'paytirishni bekor qiladi.

$$\sqrt{y}=\frac{x}{\sqrt{x^{4}}}$$

x ni \sqrt{x^{4}} ga bo'lish.

$$\sqrt{y}=\frac{1}{x}$$

Tenglamaning ikkala taraf kvadratini chiqarish.

$$y=\frac{1}{x^{2}}$$

x uchun yechish

$$\left\{\begin{matrix}x=0\text{, }&y\geq 0\\x=\frac{1}{\sqrt{y}}\text{, }&y>0\end{matrix}\right,$$
