$\textbf{Answer :}$

We do some corrections to the question.

Question be :

Rationalize the denominator of 1/(√2 + 1)

So, we rationalize the denominator by multiplying both the numerator and the denominator by (√2 - 1).

Then,

1/(√2 + 1)

= (√2 - 1)/{(√2 + 1)(√2 - 1)}

= (√2 - 1)/(2 - 1)

= (√2 - 1)
