The denominator can be rationalised by Multiplying with the opposite sign of the denominator , with the same number as numerator as well as the denominator.
So , following the above step we get :
If we carefully observe the denominator ; it is in the form of (a + b) (a - b)
We know that it's expansion gives
So , we do the same.
-----> this will be our numerator
This gives us :
Thus we get :
When we interchange the places of the digits in numerator we get :

If we carefully observe the denominator ; it is in the form of (a + b) (a - b)
We know that it's expansion gives![\sf{ {a}^{2} - {b}^{2}} \sf{ {a}^{2} - {b}^{2}}](https://tex.z-dn.net/?f=%5Csf%7B%20%7Ba%7D%5E%7B2%7D%20-%20%7Bb%7D%5E%7B2%7D%7D)
So , we do the same.
This gives us :
Thus we get :
When we interchange the places of the digits in numerator we get :
Hence we have rationalised the denominator..
