1. \(\cfrac{3\sqrt7}{\sqrt5+\sqrt2}-\cfrac{5\sqrt5}{\sqrt2+\sqrt7}+\cfrac{2\sqrt2}{\sqrt7+\sqrt5}\)

2. সরল করো :
\(\cfrac{3\sqrt7}{\sqrt5+\sqrt2}-\cfrac{5\sqrt5}{\sqrt2+\sqrt7}+\cfrac{2\sqrt2}{\sqrt7+\sqrt5}\) Madhyamik 2016

3. সরলতম মান নির্ণয় করি: \(\sqrt{12}+\sqrt{18}+\sqrt{27}-\sqrt{32}\)

4. সরল করি: \(\cfrac{5}{\sqrt2+\sqrt3}\) \(-\cfrac{1}{\sqrt2-\sqrt3}\)

5. \(\cfrac{\sqrt2 (2+\sqrt3)}{\sqrt3 (\sqrt3+1)}- \cfrac{\sqrt2 (2-\sqrt3)}{\sqrt3 (\sqrt3-1)} \)

6. \(\cfrac{4√3}{2-√2}-\cfrac{30}{4√3-\sqrt{18}}-\cfrac{\sqrt{18}}{3-\sqrt{12}}\)

7. \(\cfrac{3√2}{√3+√6}-\cfrac{4√3}{√6+√2}+\cfrac{√6}{√2+√3}\)

8. সরল করি: \(\cfrac{x+\sqrt{x^2-1}}{x-\sqrt{x^2-1}}+\cfrac{x-\sqrt{x^2-1}}{x+\sqrt{x^2-1}}\) সরলফল 14 হলে, \(x\) এর মান কী কী হবে হিসাব করে লিখি ।
