giai pt . giup minh vs
\(2-x^2=\sqrt{2-x}\)
2 ) Giai pt :
a ) \(\sqrt{9x^2}=2x+1\)
b ) \(\sqrt{x^2+6x}+9=3x-1\)
giải pt \(\frac{2+\sqrt{x}}{\sqrt{2}+\sqrt{2+\sqrt{x}}}+\frac{2-\sqrt{x}}{\sqrt{2}-\sqrt{2-\sqrt{x}}}=\sqrt{2}\)
Giải pt sau:
\(\frac{2+\sqrt{x}}{\sqrt{2}+\sqrt{2+\sqrt{x}}}+\frac{2-\sqrt{x}}{\sqrt{2}-\sqrt{2-\sqrt{x}}}=\sqrt{2}\)
Giải pt: \(x^2+\left(3-\sqrt{x^2+2}\right)x=1+2\sqrt{x^2+2}\)
Giải pt
\(\sqrt{2x+\frac{2013-1}{\sqrt{2-x^2}}}-\sqrt[3]{2014-\frac{2013-1}{\sqrt{2-x^2}}}=\sqrt{x+2013}-\sqrt[3]{x+1}\)
Giải pt: \(4\sqrt{x+\sqrt{x^2-1}}=9\left(x-1\right)\sqrt{2x-2}\)
giải PT:
a, \(1-\sqrt{x-1}=\sqrt{x}-\frac{2}{3}\sqrt{x-x^2}\)
b, \(\sqrt{x+\sqrt{x^2-1}}=\frac{9\sqrt{2}}{4}\left(x-1\right)\sqrt{x-1}\)
help me !!!!!!
Giải các hệ pt sau
a, \(\sqrt{\frac{x^2}{4}+\sqrt{x^2-4}}=8-x^2\)
b, \(\sqrt{3x^2+x-4}=2-2x\)
