Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

$\frac{ \sqrt{3} - 1 }{ \sqrt{3} + 1} \times \frac{\sqrt{3} - 1}{\sqrt{3} - 1} = a + b \sqrt{3}$

$\frac{ {( \sqrt{3} + 1) }^{2} }{3 - 1} = a + b \sqrt{3}$

$\frac{3 + 1 - 2 \sqrt{3} }{2} = a + b \sqrt{3}$

$2 - \sqrt{3} = a + b \sqrt{3}$

Comparing the coefficients

a = 2 and b = - 1
