To solve the equation \(\frac{\sqrt{3}-1}{\sqrt{3}+1} = a + b\sqrt{3}\), where \(a\) and \(b\) are rational numbers, we will rationalize the left-hand side of the equation. ### Step-by-Step Solution: 1. **Rationalize the Denominator**: To rationalize the denominator, we multiply the numerator and the denominator by the conjugate of the denominator, which is \(\sqrt{3}-1\): \[ \frac{\sqrt{3}-1}{\sqrt{3}+1} \cdot \frac{\sqrt{3}-1}{\sqrt{3}-1} = \frac{(\sqrt{3}-1)^2}{(\sqrt{3}+1)(\sqrt{3}-1)} ...
