One of the consequences of this theorem is that every polynomial with real coefficients will have an even number of complex roots. That even number may be zero, or it will be two, four, six, etc. ... we get 8 cos 3π 2 +8i sin 3π 2 =0+8i -1 ... square root is a 1/2 exponent, cube root is a 1/3 exponent and so forth). The rooting process is ...
