So many people in the replies here are totally missing the point. Yes, there is an infinite number of valid possible answers for i^i. But EVERY SINGLE ONE OF THEM IS A REAL NUMBER. https://x.com/mathladyhazel/status/1800905395961241811

Are you looking for an explanation that shows the algebraic steps to prove it? Or just, the idea in general, without math stuff shown?

Hmmm I tried for quite awhile, but couldn’t come up with a clear way of describing it conceptually. I kept falling back on showing it algebraically lol, sorry. But now I see that Vitalik has explained it in the comments in a very nice, clear, concise way (quoted below). We can think of the number 𝑖 as an action: a rotation by 90Β°. And we can think of raising something to the power of 𝑖 as a rotating action upon that action: a 90Β° rotation of the act of rotating 90Β°. I think the reason it’s not intuitive, is because most of us learned that β€œexponentiation is repeated multiplication.” When that’s an oversimplification that doesn’t work once we get to complex numbers. Sorry I couldn’t come up with a better explanation! But I think Vitalik’s nails it perfectly anyway! https://warpcast.com/vitalik.eth/0xd941680b
