Step-by-step explanation:
(√3 - 1)/(√3 + 1) * (√3 - 1)/(√3 - 1)
[ multiply both numerator and denominator by the conjugate of the denominator ]
=> (√3 - 1)²/(3 - 1) [ (√3 + 1)(√3 - 1) = 3 - 1 => 2 ]
=> (3 + 1 - 2√3)/2
=> (4 - 2√3)/2
=> 2 (2 - √3) / 2
=> 2 - √3
=> 2 - 1.732
=> 0. 268 ~ 0.2679 => option b
