Question

Correct answer
√2 +1 +1/√2+1
=√2+1 + 1/√2+1 ×√2/1/√2-1
=√2+1 +√2-1 /(√2+1 )(√2-1) that means a^2 - b^2
√2+1 + √2-1 ÷ √2^ -1^2
√2+1 +√2 -1 ÷2 -1
2√2 ÷1
Answer 2√2

Answer 1

Answer:

2√2-2

Step-by-step explanation:

x=√2+1

∴ x+(1/x)

=(√2+1)+{1+(√2+1)}

=(√2+1)+[(√2-1)/{(√2)²-(1)²}]

=(√2-1)+(√2-1)

=2√2-2....[Ans]

I THINK THIS WILL BE THE ANSWER.
