I think at this point mine is just iⁱ≈⅕

It's so surprising! Raise i to anything real, get a complex number with magnitude 1. Raise anything real to i, get a complex number with magnitude 1. Raise i to itself, you just get about a fifth.

It's equal to something, just left as an exercise to the reader. Which is everyone's favorite, really.

WolframAlpha gives a solution in the form of the upper incomplete gamma function, which seems a bit like cheating.

Lately, I'm a fan of any sufficient condition for strong duality, in particular Slater's condition.

I take your 1/5 and raise you iⁱ≈1/sqrt(20+pi), to a frankly ridiculous number of decimal places.
One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision - BR

Today I learned that 5 is a frankly ridiculous number. This comports well with our existing knowledge that infinity and 5 are effectively indistinguishable.

Therefore the solution set to the polynomial equation x2 - x = 0 is x ∈ {0,1} = 2.

x∈2. It just sounds wrong.

But x≠{} and x≠{{}}.

What was I smoking yesterday? Of course it is, but it's still, just, wrong.
