Exercise 12. Answer the following question in a typed computer writing nothand written. Solve step-wise showing clearly all steps.Exercise 1.12 Let M = (123). Compute two different simplified row reduced formsof M. Conclude that the simplified row reduced form of a matrix is not unique (see Re-mark 1.6.2).Proposition 1.6.2 Let M be a matrix and N a matrix obtained from M by elementary operations.Then M and N have the same row rank.Proof It follows from Lemma 1.6.1 that the subspace of R" generated by the rows of M €M(mx n, R) is equal to the subspace generated by the rows of N.
