I know, from computing experience, that the cube root of 27 is 3.
or again, 3, -3, -3. I can test for truth by multiplying these roots and
getting back to 27.
But invoking the complex plane will produce results that may seem puzzling:
On the complex plane, these other roots also verify 27. That is de Moivre's theorem, 1707.
As for the cube root of -27, I know that -3 is one such root. On the complex plane:
Each of the three cited roots is a root in itself.
same vein, 3 can be a factor to -27, but cannot be considered a cube root...👩🦰
