3. (i) morphisms State what it means for a sequence of left R-module MNPQ to be "exact". (ii) Let f: Z² Z² and g: Z² → Z be the morphisms given by f(a, b) = (2a + 3b, 6a +9b) and Show that the sequence is exact. g(x, y) = y-3x. z²Z²Z-0 (iii) State what is meant by a "short" exact sequence, and what it means for a short exact sequence to be "split".
