WebNote: (i) The two determinants to be multiplied must be of the same order. (ii) To get the T mn (term in the m th row n th column) in the product, Take the m th row of the 1 st determinant and multiply it by the corresponding terms of the n th column of the 2 nd determinant and add. (iii) This method is the row by column multiplication rule for the … WebDeterminants are calculated for square matrices only. If the determinant of a matrix is zero, it is called a singular determinant and if it is one, then it is known as unimodular . For the system of equations to have a unique solution, the determinant of the matrix must be nonsingular, that is its value must be nonzero.
