i^x = 2

I was watching with fascination this video which shows how to solve:

i^x = 2

Having never done complex maths at school, this is quite a brain warp.

But I was very impressed that if you let

x = -2·ln2·i/π

The HP-15c, DM42, TI-83+ and RPN83P got the correct answer. My fx-115W and fx-992s didn't.
