The first post said "Use exactly four 9s and any number of arithmethic or higher level math operations." If the operation can be expressed by symbols without numeric terms it seems to be allowed: log (x), !, etc.
The issue here is whether to allow the symbol for square root because by convention the exponent 2 is omitted, while cubic root, for example, is not allowed because the exponent 3 must be written. The 9th root of nine, however, would have to be allowed, unquestionably, but it uses two of the four 9s allowed and is useless anyway.
We need to ask the third umpire.

I have a way to do it but I am not going to.
Consider
ln e = 1,
e/e = 1,
ln pi / ln pi = 1
pi / pi = 1
We can have number 1 without using any 9s.
But I won’t use it because it defects the purpose of this thread.
It is a bit like the stuff lawyers do. Legitimate but very very dodgy.Visit my website at www.myFineWoodWork.com

11th March 2008, 12:48 PM #53Have you found how to legitimately get 1 from only one 9?
I have been trying to do exactly that. If I could crack that I could crack 67. No luck so far.Visit my website at www.myFineWoodWork.com

infinite root of 9

Infinite root of 9 doesn't make it 1.
I think the real solution does exist though. The truth is out there.Visit my website at www.myFineWoodWork.com

limit is an approximation.
What is 9 divided by infinity then? Don't tell me it is 0.

I guess you are one of those who still refuse to accept that 0.99999... recurrent is =1, then. You are fighting a rearguard battle, but if that's what lifts your boat...
I'm not a good enough mathematician to follow you down that path.
Just to amuse me: assuming that you could get 1 from one 9, how do you get 67? It still baffles me.

Hang on mate!!
0.99999... is not 1. Why is it so hard to understand?
