Rationalise √ 3-1/ √ 3+1

Given √3+1/√3-1

We need to rationalize the givenequation

To rationalize we will multiply and divide the denominator by √3+1

(√3+1)√3+1)/(√3-1)(√3+1)

Denominator can be simplified using the identity (a2-b2)=(a-b)(a+b)
And the equation becomes
=(√3+1)2/(√3)2-(1)2
=(4+2√3)/2
=2+√3
