Question

analyse the Nationalised the denominator root 3 minus 1 by root 3 + 1​

Answer 1

Answer:

√3-1/√3+1, by rationalising we will get (√3-1/√3+1)= (√3-1/√3+1) ×√3-1/√3-1 = (√3-1)^2/ 3-1 = 3+1-2√3 /3-1= 4-2√3 /2 = 4/2-2√3/2 = 2-√3

Answer 2

Answer:

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
