Find the rationalisation factor
\[ 2 + \sqrt{3} \]
Solution:
\[ \text{Rationalisation factor of } (2 + \sqrt{3}) = (2 – \sqrt{3}) \]
\[ \because (2 + \sqrt{3})(2 – \sqrt{3}) = 4 – 3 = 1 \]
\[ \therefore \text{Answer: } 2 – \sqrt{3} \]
\[ 2 + \sqrt{3} \]
\[ \text{Rationalisation factor of } (2 + \sqrt{3}) = (2 – \sqrt{3}) \]
\[ \because (2 + \sqrt{3})(2 – \sqrt{3}) = 4 – 3 = 1 \]
\[ \therefore \text{Answer: } 2 – \sqrt{3} \]
