SUMMARY
The embeddings of the field K=Q(i,(1+i)^(1/3)) in the complex numbers C are primarily determined by the identity mapping. For the rational field Q, the only embedding is indeed the identity function, as it must map 1 to 1 and natural numbers to natural numbers. The discussion highlights that K has multiple embeddings, specifically around the choices for the imaginary unit i, which can map to either i or -i, along with variations involving the cubic root of (1+i).
