I Tiny URL'd that becuase the actual link screws up.

Also I dont get how this proof

http://community.boredofstudies.org...unsw-mathematics-competition.html#post4206829

Can be used to prove it for Root 6 Repeated.

I know the answer but I need that finite proof.

Thanks in advance

What exactly do you want done with the first question?

I needa know how to start and where to continue. Like grouping which sets

 

[khorne]

so sqrt(6+sqrt (6+sqrt 6....))

Well, you can do it a simple way: like

x = sqrt(6+sqrt (6+sqrt 6....))
x^2 = 6 + sqrt(6+sqrt (6+sqrt 6....))
x^2 - x = 6
x^2-x-6 = 0
(x-3)(x+2) = 0
therefore x tends towards 3

1. factorise. 2. let 1=6

I tried factorising, I've spent a few hours and still have to start from scratch
