Answer 2

Answer:

2-root3

Step-by-step explanation:

$\frac{\sqrt{3}-1}{\sqrt{3}+1 }$

multiply both numerator and denominate with the conjugate of the denominator which is

$\frac{\sqrt{3}-1 }{\sqrt{3}+1 }*\frac{\sqrt{3}-1}{\sqrt{3}-1} \\\frac{(\sqrt{3}-1)^{2} }{(\sqrt{3} ^{2} )-(1^{2}) } \\\frac{3-2\sqrt{3}+1 }{3-1}$

therefore the denominator is rationalized to

$\frac{4-2\sqrt{3} }{2} \\by simpliying\\we get\\2-\sqrt{3}$
