(2) Let K | F be a field extension and A € M₁ (F). Denote its minimal polynomial by A,F, and denote it by A,K if we consider A as an element of Mn(K). From the definition of minimal polynomials it's clear that μA,K divides A,F in K[x]. Explain why here (as opposed to the situation for mini- mal polynomials of elements of field extensions) we always have μA,K = μA,F. Remark: There are multiple ways to approach this question.
