a) $\frac{\sqrt{x+1}}{x-1}+\frac{\sqrt{x+17}}{x-17}+\frac{x}{x^{2}-1}=0$b) $\frac{\sqrt{x-3}}{x}+\frac{2\sqrt{x+4}}{x^{2}}=\frac{x-1}{3x}$
c) $\frac{\sqrt[3]{x-1}}{x}-\frac{2-\sqrt{x-1}}{x^{2}}=\frac{1}{x^{2}}$
d) $\frac{\sqrt[3]{x-1}-2x}{6-x}=\frac{2x-2}{\sqrt{x}}$
e) $(2x-1)\sqrt{x-1}+(x-3)\sqrt{x+17}=x^{2}+1$
