I'd like to close this Question ith root of a complex number as a duplicate of one of the posts asking about $i^i$, but I didn't spot one in a quick search. It seems like it ought to be covered by an abstract duplicate entry.
@hardmath I'm all for having a good abstract dupe target for similar questions, but I feel like that one can be closed as "lacking context" without much need to overthink it
Note this repost of the question I last linked to. The account from which that question (linked above) was deleted; now we have the first part reasked: math.stackexchange.com/questions/2709308/…
Wow... that was quickly deleted (my most recently linked question.)
@XanderHenderson I've cast a vote to close it. No one can say you didn't extend patience and time to help the asker move forward. It is a rather bitter pill to swallow that despite such patience and hints and suggestions, some askers will not lift a finger, and are simply waiting (here, in vain) for someone to "do their work for them."
