GIÚP MK ĐI!!!!!!!!
Giải pt: \(\frac{\sqrt{x+1}}{\sqrt{x+1}-\sqrt{3-x}}=x-\frac{1}{2}\)
giải pt \(10+\sqrt{3}x^3+3x+\frac{\sqrt{3}}{x^3}=5\sqrt{3}x^3+2x+\frac{2\sqrt{3}-1}{x}+\frac{5}{x^2}\)
giải pt \(\sqrt{2x+\frac{2013x-1}{\sqrt{2-x^2}}}-\sqrt[3]{2014-\frac{2013x-1}{\sqrt{2-x^2}}}=\sqrt{x+2003}-\sqrt[3]{x+1}\)
giải pt \(\sqrt{2x+\frac{2013x-1}{\sqrt{2-x^2}}}-\sqrt[3]{2014-\frac{2013x-1}{\sqrt{2-x^2}}}=\sqrt{x+2013}-\sqrt[3]{x+1}\)
Giải pt:
\(\sqrt{2x+\frac{2013x-1}{\sqrt{2-x^2}}}-\sqrt[3]{2014-\frac{2013x-1}{\sqrt{2-x^2}}}=\sqrt{x+2013}-\sqrt[3]{x+1}\)
