If A= [ array ll 3 & 4 5 & 6 7 & 8 array ] and B= [ array lll 3 & 5 & 7 4 & 6 & 8 array ] , then which one of the following is correct?

Options

  1. AB is the inverse of A
  2. BB is the adjoint of A
  3. CB is the transpose of A
  4. DNone of the above

Correct answer

C. B is the transpose of A

Step-by-step solution

A = [ array ll 3 & 4 5 & 6 7 & 8 array ], A ^ T = [ array lll 3 & 5 & 7 4 & 6 & 8 array ], B = [ array lll 3 & 5 & 7 4 & 6 & 8 array ] B is the transpose of A .
