We will discuss the relation between sparse mixeddiscriminants and the resultant of the given polynomials and their toric jacobian,which yields a multiplicativity formula for sparse mixed discriminants. We willalso give conditions for mixed discriminants to be computed via iterateddiscriminants and will describe possible extra factors coming from thesingularities of the discriminantal locus.
