It turns out that square roots of complex numbers are always other complex numbers. 2 2 4 -2 -2. Real axis and has distance of 1 from the origin.
This is because the square of either one is 4. In my discipline at least it comes up about half as often as the square root of 2 does --- that is it isnt rare but it arises only because of our prejudice for things which can be expressed using small integers. Begingroup The square root of i is 1 isqrt2.
