Rationalise the denominator of `1/(2+sqrt(3))`

Explanation

To rationalize the denominator of the expression \( \frac{1}{2 + \sqrt{3}} \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the expression**: We have the expression \( \frac{1}{2 + \sqrt{3}} \).

2. **Multiply by the conjugate**: To rationalize the denominator, we multiply both the numerator and the denominator by the conjugate of the denominator. The conjugate of \( 2 + \sqrt{3} \) is \( 2 - \sqrt{3} \). Thus, we multiply:
\[
