Gilgameshes, post the hardest math problem

...you've ever encountered

Well, any hitherto unsolved one would generally be a good start.
Here you are, go nuts:

Race you to the 3n + 1 conjecture?

if x = square root of pi
and 10x = n
and 56 n = v
and 40 v = r
and 20 r = e
and 69 e = w
and 33 w = l
and 9 l = d
and 99 d = i
what does "i - will - never - die" = ? up to 30 dp?

if you manage to figure this out, it means that you have huge ammounts of time on your hands...not the hardest math problem but its probably the most tedious in terms of basic algebra

Underage b&, what are you, third grade or something? It took me three minutes to get the answer

Exact solution: -25176309760000000000*pi^(5/2)-29236672477950341610995712000000000000*%pi^2-3738353075458670592000000000*
pi^(3/2)+908905536000*sqrt(pi)

If you want to see some real annoying algebraic manipulation, look at differential geometry.  They love them sub&super scripts.
