Answer:
To solve this question, we will have to rationalize the denominator.
Rationalizing the denominator:-
7+ root 5/ 7- root 5
using the identity (a+b)(a-b)= a square - b square, we will multiply the numerator and denominator by 7+ root 5
= (7+ root 5)(7+ root 5)/ (7- root 5)(7+ root 5)
=54+14 root 2/ 7 square - root 5 square
54+ 14 root 2/ 44
