19. Let A be any m × n matrix. If U and V are two reduced row echelonmatrices obtained from A by applying two sequences of elementary row operations E₁,..., Epand F₁,..., Fa, so thatU = EpE₁A and V=F₁ F₁A,F₁. In other words, the reduced row echelon form of anythen UV and Epmatrix is unique..…..E₁ = F₁
