- A countably infinite number, I do believe. --jpgordon𝄢𝄆 𝄐𝄇 04:14, 20 March 2017 (UTC)
- The values are e2kπ − i ln 2, for any integer k. Double sharp (talk) 05:32, 20 March 2017 (UTC)
- x=2−i. Bo Jacoby (talk) 07:31, 20 March 2017 (UTC).
- @Bo Jacoby: Did you mean 2(1/i) ? --CiaPan (talk) 09:58, 22 March 2017 (UTC)
- The two expressions are equal, --JBL (talk) 12:46, 22 March 2017 (UTC)
- Oh, you're right! Just missed it's an imaginary number. :) --CiaPan (talk) 12:55, 22 March 2017 (UTC)
