Pick out the wrong statement. If A and B are square matrices of the same order, then

Options

  1. AA+B=B+A
  2. B(A B)^ =B^ A^
  3. CA-B=I
  4. D|A B|=|A||B|

Correct answer

C. A-B=I

Step-by-step solution

The only wrong statement is option(c). It is not necessary that A-B=I, A, B square matrix of same order.
