Giải các phương trình sau:
a, \(\sqrt{x-\frac{1}{x}}+\sqrt{1-\frac{1}{x}}=x\)
b, \(\sqrt{\frac{x^3+1}{x+3}}\sqrt{x+1}=\sqrt{x^2-x+1}+\sqrt{x+3}\)
c, \(\sqrt{x\left(x-1\right)}+\sqrt{x\left(x+2\right)}=2\sqrt{x^2}\)
d, \(\sqrt{x^2-\frac{7}{x^2}}\sqrt{x-\frac{7}{x^2}}=x\)
e, \(\sqrt{\frac{5}{4}-x^2+\sqrt{1-x^2}}+\sqrt{\frac{5}{4}-x^2-\sqrt{1-x^2}}=x+1\)
g, \(\sqrt{7-x^2+x\sqrt{x+5}}=\sqrt{3-2x-x^2}\)
h, \(\sqrt{x+2\sqrt{x-1}}+\sqrt{x-2\sqrt{x-1}}=\frac{x+3}{2}\)
i, \(\sqrt[3]{x+34}-\sqrt[3]{x-3}=1\)
k, \(\sqrt[3]{3x-1}+\sqrt[3]{2x-1}=\sqrt[3]{5x+1}\)
