\(\frac{1}{\sqrt{x+1}+1}+\frac{1}{\sqrt{x+4}+2}+\frac{1}{\sqrt{x+9}+3}+\frac{1}{\sqrt{x+16}+4}=\frac{1}{\sqrt{x+100}+10}\)
tìm x=?
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
giải các phương trình : c) \(\sqrt{2x+3}\) - x = 0 ; e) \(\sqrt{3x+7}\) - \(\sqrt{x+1}\)= 2 ; f) \(\sqrt{x^2-3x+3}\) + \(\sqrt{x^2-3x-16}\) = 4 ; g) \(\sqrt{x+4}\) - \(\sqrt{1-x}\) = \(\sqrt{1-2x}\) ; h) x2 - 4\(\sqrt{x^2-2x+16}\) = 2x - 9
rut gon P=(\(\frac{3\sqrt{x}}{\sqrt{x}+2}+\frac{\sqrt{x}}{\sqrt{x}-2}-\frac{x-\sqrt{x}}{x-4}\)):\(\left(\frac{3\sqrt{x}}{\sqrt{x}+2}\right)\)
1, \(x^3-x-3=2\sqrt{6x-x^2}\)
2, \(x^3+6x^2-171x-40\left(x+1\right)\sqrt{5x-1}+20=0\)
3, \(\sqrt[3]{x+3}+\sqrt[3]{x-3}=\sqrt[5]{x-5}+\sqrt[5]{x+5}\)
4. \(\left(\frac{1}{\sqrt{x}}-\frac{\sqrt{x}}{x+1}\right)^2=\frac{4\left(1+\sqrt{1+4x}\right)}{x+1+\sqrt{x^2+3x+2}}\)
Giải phương trình
\(\sqrt[4]{(x-1)^2} - \sqrt[4]{(x+1)^2} = \frac{3}{2} \sqrt[4]{x^2 -1}\)
giải phương trình sau
\(\frac{2\sqrt{2}}{\sqrt{x+1}}+\sqrt{x}=\sqrt{x+9}\)
Cho A = \(\frac{x^2-\sqrt{x}}{x+\sqrt{x+1}}-\frac{x^2+\sqrt{x}}{x-\sqrt{x+1}}\)
Rút gọn B= 1-\(\sqrt{2}\sqrt{A+2x+\frac{1}{2}}\) với 0 \(\le\)x\(\le\)1/4
\(\sqrt{\frac{6}{2-x}}+\sqrt{\frac{10}{3-x}}=4\)
