Q3 of 81 Page 157

Let us write a rationalizing factor of the denominator of which is not its conjugate surd.

Given:  

Conjugate surd for the given expression will be (√3 + 2), So we have to find a factor other than this

Rationalize with


We get,






So,  will be a rationalizing factor to the given expression without being its conjugation surd
