A) Property number 3: If square matrix B is obtained from square matrix A by multiplying each element of any row (or column) of A by some real number k , then | B | = k | A |.
B) Property number 2: If square matrix B is obtained from square matrix A by interchanging two rows (or two columns) , then | B | = −- | A |.
C) Property number 4: If square matrix B is obtained from square matrix A by adding k times a row (or column) of A to another row (or column) of A , then | B | = | A |.
D) Property number 1: If any row (or column) of a square matrix A contains only zeros, then | A | = 0.
E) Property number 5: If two rows (or columns) of a square matrix A are identical, then | A | = 0.
