(Trees II) Let G = (V,E) be a connected graph together

(Trees II) Let G = (V,E) be a connected graph together with a weight function w. E-R (a) Let T be a minimum spanning tree of G. Let e' = {a,b) e E be an edge of G which is not contained in T. Let e be any edge on the unique simple path from a to b in T. Show that w(e)
