1.\(\sqrt{\frac{\left(1-x\right)}{x}}=\frac{\left(2x+x^2\right)}{1+x^2}\)
2. 3(2-\(\sqrt{x+2}\))=2x+\(\sqrt{x+6}\)
3. \(\sqrt[3]{x+2}+\sqrt[3]{x+1}=\sqrt[2]{2x^2}+\sqrt[3]{2x^2+1}\)
4. \(\sqrt[3]{x+24}+\sqrt{12-x}=6\)
Toán 10 ạ, giúp em với
\(\sqrt{2x-4+2\sqrt{2x-5}}\) \(+\sqrt{2x+4+6\sqrt{2x-5}}=14\)
help me ( đang cần gấp )

\(\sqrt{2x^2+8x+6}-\sqrt{x^2-1}=2x+2\)
Giai pt
1,\(\sqrt{x+8-6\sqrt{x-1}}\)=4
2,\(\sqrt{x+6-2\sqrt{x+2}}\)+\(\sqrt{x+11-6\sqrt{x+2}}\)=1
3,\(\sqrt{x-3-2\sqrt{x-4}}\)+\(\sqrt{x-4\sqrt{x-4}}\)=1
4,\(\sqrt{x-2+\sqrt{2x+5}}\)+\(\sqrt{x+2+3\sqrt{2x-5}}\)=\(\dfrac{7}{2}\)
5,\(\sqrt{2x+4+6\sqrt{2x-5}}\)+\(\sqrt{2x-4-2\sqrt{2x-5}}\)=4
6,\(\sqrt{\dfrac{1}{4}x^2+x+1}\)-\(\sqrt{6-2\sqrt{5}}\)=0
7,x+\(\sqrt{x+\dfrac{1}{2}}\)+\(\sqrt{x+\dfrac{1}{4}}\)=2
8,\(\sqrt{\left(x-1\right)+4-4\sqrt{x-1}}+\sqrt{x-1-6\sqrt{x-1+9}}\)=1
9,\(\sqrt{x+2\sqrt{x-1}}\)+\(\sqrt{x-2\sqrt{x-1}}\)=\(\dfrac{x+3}{2}\)
x^2-2(x+1)\(\sqrt{3x+1}\)=2\(\sqrt{2x^2+5x+2}\)-8x-5
Giải phương trình:
1) \(\sqrt{x+3-4\sqrt{x-1}}+\sqrt{x+8-6\sqrt{x-1}}=1\)
2) \(\sqrt{x+2+3\sqrt{2x-5}}+\sqrt{x-2-\sqrt{2x-5}}=2\sqrt{2}\)
\(\sqrt{x^3+1}+\sqrt{x^3+8}+\dfrac{x}{2}=\sqrt{2x^4+32}\).

2 ( 2x+1 ) \sqrt{ x+1 } + ( 4-x ) \sqrt{ 2-2x } = 6 \sqrt{ x ^{ 2 } +2 }
Giải phương trình :
a. (\(\sqrt{x+4}\) -2)(\(\sqrt{4-x}\) -2)= -2x
b. 2.\(\sqrt[3]{6x-2}\) + 3\(\sqrt{6-10x}\) = 8
c. \(\sqrt[3]{x+2}\) + \(\sqrt[3]{14-x}\) = 4
d. \(\sqrt{5x-1}\) - \(\sqrt{3x+13}\) = \(\frac{x-7}{3}\)
giúp em với đang cần gấp ạ ?
