4sqrt(5)-8
The math section is under science and mathematics.

Why would you rationalize the denominator?
4/2 + sqrt(5) = 2 + sqrt(5)
but...
4/2 +sqrt(5) = 4/2 + 2*sqrt(5)/2 = (4+2*sqrt(5))/2

I was going to say you posted this in the wrong place, but there is a lot of rationalization that goes on here.
OK, I'll take a shot. You got that out of context.

I think you posted in the wrong place.
Really, though, if I remember my algebra, you would have to square both numerator and denominator to eliminate the square root, so that gives me 16 divided by 4 plus 5. I could be wrong (believe me, it's happened before) so please do check your math.

So you like the Golden Rectangle. What's your point?
I believe the correct value is (1+SQRT(5)) / 2

Do you mean 4 / (2+squareroot5) ? How can others get the answer if they don't even know the question??

You must have heard how good we are at rationalizing here in R&S.
