If A = [a ij ], find a 13 and a 31 and state the matrix's order. If identification is not possible, state why.

Order: 2 × 3, a 13 = 3; a 31 does not exist, as there are only two rows

Order: 2 × 3, a 31 = 3; a 13 does not exist, as there are only two rows

Order: 2 × 3, a 13 = 3; a 31 = 7

Order: 2 × 3, a 13 = 3; a 31 = -3

If A = [aij], find a13 and a31 and state the matrix's order. If i...
