27 P: \( \frac{1}{\sqrt{x}-3} + \frac{1}{\sqrt{x}+3} = \frac{\sqrt{x}-9}{2\sqrt{x}} \) với \( x > 0 \) và \( x \neq 9. \)
3 P: \( \sqrt{x}+3 - \frac{\sqrt{x}-1}{\sqrt{x}-2} + \frac{4\sqrt{x}-4}{h-x} \)
47 P: \( \sqrt{x}-y \sqrt{x} \)
5 P: \( \frac{1}{(1-\sqrt{x})} + \frac{1}{(1+\sqrt{x})} \)
6 P: \( \left( \frac{4}{\sqrt{x}+1} - \frac{1}{x-2\sqrt{x}} \right) \)
7 P: \( \frac{x}{\sqrt{x}-1} = -\left( \frac{\sqrt{x}+1}{\sqrt{x}} - \frac{1}{\sqrt{x}-1} + \frac{2-x}{x-\sqrt{x}} \right) \)
