Question

If A and B are non-singular square matrices of same order, then a d j left parenthesis A B right parenthesis is equal to

  1. left parenthesis a d j A right parenthesis left parenthesis a d j B right parenthesis    
  2. left parenthesis a d j B right parenthesis left parenthesis a d j A right parenthesis    
  3. left parenthesis a d j B to the power of negative 1 end exponent right parenthesis left parenthesis a d j A to the power of negative 1 end exponent right parenthesis    
  4. left parenthesis a d j A to the power of negative 1 end exponent right parenthesis left parenthesis a d j B to the power of negative 1 end exponent right parenthesis    

The correct answer is: left parenthesis a d j B right parenthesis left parenthesis a d j A right parenthesis


    It is obvious.
