Detailed Solution\(= \frac{2\sqrt{2}  \sqrt{3}}{\sqrt{2} + \sqrt{3}} \times \frac{\sqrt{2}  \sqrt{3}}{\sqrt{2}  \sqrt{3}}\)\(= \frac{2\sqrt{2}(\sqrt{2}) + (2\sqrt{2})(\sqrt{3})\sqrt{3}(\sqrt{2})\sqrt{3}(\sqrt{3})}{(\sqrt{2})^2(\sqrt{3})^2}\) \(= \frac{2 \times 2  2\sqrt{6}  \sqrt{6} + 3}{2  3}\) \(= \frac{4  3\sqrt{6} + 3}{1}\) \(= \frac{7  3\sqrt{6}}{1}\) \(= \frac{7}{1}  \frac{3\sqrt{6}}{1}\) \(= 7 + 3\sqrt{6}\) \(= 3\sqrt{6}7\) There is an explanation video available below.
