Answer 2

Answer:

Here, the after rationalising it, we would get=(root2-1)/1

Step-by-step explanation:

According to given question,

=1/(root2+1)

=1/(root+1)×(root2-1)/(root2-1)

=(root2-1)/(root2)^2-1 (As in the denominator, (a+b)×(a-b)=(a^2-b^2)

=(root2-1)/2-1 (square of root2 =2)

=(root2-1)/1

=root2-1 (Answer).

Thank you.
