Question 156

Multiple Choice

Use the appropriate property of determinants from this section to justify the true statement. ∣69118−10365−1∣=−∣611983−106−15∣\left| \begin{array} { c c c } 6 & 9 & 11 \\8 & - 10 & 3 \\6 & 5 & - 1\end{array} \right| = - \left| \begin{array} { c c c } 6 & 11 & 9 \\8 & 3 & - 10 \\6 & - 1 & 5\end{array} \right| Do not evaluate the determinants.


A) Property number 1: If any row (or column) of a square matrix A contains only zeros, then | A | = 0.
B) 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 |.
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 2: If square matrix B is obtained from square matrix A by interchanging two rows (or two columns) , then | B | = −- | A |.
E) Property number 5: If two rows (or columns) of a square matrix A are identical, then | A | = 0.
