Rationalise (2√6 − √5)/(3√5 − 2√6)

🎥 Video Solution:


📘 Rationalise & Simplify:

\[ \frac{2\sqrt{6} – \sqrt{5}}{3\sqrt{5} – 2\sqrt{6}} \]

✏️ Solution:

\[ = \frac{2\sqrt{6} – \sqrt{5}}{3\sqrt{5} – 2\sqrt{6}} \times \frac{3\sqrt{5} + 2\sqrt{6}}{3\sqrt{5} + 2\sqrt{6}} \]

\[ = \frac{(2\sqrt{6} – \sqrt{5})(3\sqrt{5} + 2\sqrt{6})}{(3\sqrt{5})^2 – (2\sqrt{6})^2} \]

\[ = \frac{6\sqrt{30} + 24 – 15 – 2\sqrt{30}}{45 – 24} \]

\[ = \frac{4\sqrt{30} + 9}{21} \]

✅ Final Answer: \(\frac{4\sqrt{30} + 9}{21}\)
