  4 + 3√5  

 4 - 3√5

We have to remove roots from denominator

so

 ( 4 + 3√5) (4+ 3√5)  

 (4 - 3√5) (4+3√5)


  (4 + 3√5)²  

 4² - (3√5)²


  16 + 12√5 + 45      =      - ( 61 + 12√5)  

    16 - 45                               9


3.  2/√5   for this multiply up and down with √5 . then you will et 2√5/5
