C1,Giải hệ \(\hept{\begin{cases}\sqrt[4]{x^3}+\sqrt[5]{y^3}=35\\\sqrt[4]{x}+\sqrt[5]{y}=5\end{cases}}\)
C2, Giải pt \(x\sqrt{x}+\left(1-x\right)\sqrt{1-x}=\sqrt{x}+2\sqrt{1-x}\)
Giaỉ hệ pt:
\(\left\{{}\begin{matrix}x+y-2=4\sqrt{z-2}\\y+z-2=4\sqrt{x-2}\\x+z-2=4\sqrt{y-2}\end{matrix}\right.\)
Cảm ơn mn ạ
\(\left\{{}\begin{matrix}\sqrt{3x}.\left(1+\dfrac{1}{x+y}\right)=2\\\sqrt{7y}.\left(1-\dfrac{1}{x-y}\right)=4\sqrt{2}\end{matrix}\right.\)
Giải hệ pt
Giải hệ PT:\(\left\{{}\begin{matrix}\dfrac{4}{\sqrt[]{2x-y}}-\dfrac{21}{x+y}=\dfrac{1}{2}\\\dfrac{3}{\sqrt{2x-y}}+\dfrac{7-x-y}{x+y}=1\end{matrix}\right.\)
Giải hệ pt:
\(\hept{\begin{cases}2\sqrt{x+y}+2\sqrt{x-y}=4+\sqrt{x^2-y^2}\\\sqrt{x}+\sqrt{y}=2\end{cases}}\)
