( e i ( π / 2 + 2 k π ) ) x = e i x ( π / 2 + 2 k π ) .

Take Take c∈C arbitrarily. One might define i c := e ln ( i c ) = e c ln ( i ) = e c i π 2 , which works. There is a catch though: this makes use of the logarithm, which is not nicely defined on the entire complex plane. The set of all 'reasonable' outcomes for i c would be e i c ( π 2 + 2 k π ) for k Z . Hence, it is not uniquely defined. This problem already arises when taking rational powers of i though, so nothing's really changed.
