Best ResponseYou've already chosen the best response.0Actually, (1+square root 5) and (1square root 5) are conjugates of each other. Since you mention denominators, do you mean the problem should be as follows: (1+square root 5)/(1square root 5)? If so, then the following solution can be arrived at: [(1+square root 5)/(1square root 5)]*[(1+square root 5)/(1+square root 5)] [1+2(square root 5)+5]/(15)=[6+2(square root 5]/4 Therefore, the answer is: (3+square root 5)/2
