If A = 1 2 3 4 5 6 and B = 1 4 2 5 3 6 , then the determinant value of B A is

Options

  1. A8
  2. B0
  3. C- 8
  4. D24

Correct answer

B. 0

Step-by-step solution

B A = 1 4 2 5 3 6 1 2 3 4 5 6 = 17 22 27 22 29 36 27 36 45 B A = 17 5 5 22 7 7 27 9 9 (Using C 3 → C 3 - C 2 and C 2 → C 2 - C 1 ) Hence, B A = 0
