hey Piyuu see mm u know this q. is difficult

I'm so bad in maths...if u have any quarry in science then ask me okay..?

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
