Rationalise (3√2 + 1)/(2√5 − 3)

🎥 Video Solution:


📘 Rationalise:

\[ \frac{3\sqrt{2} + 1}{2\sqrt{5} – 3} \]

✏️ Solution:

\[ = \frac{3\sqrt{2} + 1}{2\sqrt{5} – 3} \times \frac{2\sqrt{5} + 3}{2\sqrt{5} + 3} \]

\[ = \frac{(3\sqrt{2} + 1)(2\sqrt{5} + 3)}{(2\sqrt{5})^2 – 3^2} \]

\[ = \frac{6\sqrt{10} + 9\sqrt{2} + 2\sqrt{5} + 3}{20 – 9} \]

\[ = \frac{6\sqrt{10} + 9\sqrt{2} + 2\sqrt{5} + 3}{11} \]

✅ Final Answer: \(\frac{6\sqrt{10} + 9\sqrt{2} + 2\sqrt{5} + 3}{11}\)
