giải các phương trình:
a)\(2x^2-11x+21=3\sqrt[3]{4x-4}\)
b)\(x^3-3x^2-8x+40=8\sqrt[4]{4x+4}\)
c)\(\frac{x^2+\sqrt{3}}{x+\sqrt{x^2+\sqrt{3}}}+\frac{x^2-\sqrt{3}}{x+\sqrt{x^2+\sqrt{3}}}=x\)
1/ Tính \(A=\sqrt{24-x^2}+\sqrt{8-x^2}\)biết \(\sqrt{24-x^2}-\sqrt{8-x^2}=2\)
2/ Giải phương trình: \(\sqrt{x-2}+\sqrt{x-5}=\sqrt{x+3}\)
