Rationalizing the denominator,   .

To find :

The value of        

Rationalizing the denominator means cancelling the root values.

Now, rationalize the denominator by .

We get,              

               

                             

Using identities,  .

Applying identities in the denominator gives  

Which gives,              

                                 

                               

Given that, value for  and  

Substituting the values gives,  

                                               

                                                 

                                                 = 0.252

Hence, rationalizing the denominator gives 0.252.
