I know theorem states that rank T = Mdb(T). but what is next? Thank you very much 2. (8 marks) Let dim V = dim W = n. Let T:V → W be a linear transformation of rank k. Show that there are ordered bases B of V and D of W such that MdB(T) is a matrix that contains exactly k entries that are ls (with the rest being Os).
