    by simply using det properties we know if we multiply same no. in a row we can take it out thus 2r2 mein se 2 nikaalo and 2a is the matrices we have taken therefore take 2^order which is 3 therefore 2^3 =8 out now we got 2 *2^3 =16 out thus 16*detA = 64

      @GRAMMyt 7 місяців тому +1

      we have used both to open the determinant, Cofactor = (-1)^ i+j * M ij on putting the values of i and j we get a cofactor table
      Row 1 -> ( + - +)
      Row 2 -> ( - + -)
      Row 3 -> ( + - +)
      just apply these signs when opening a determinant, for example you open using row 2
      start with (-) and then solve the minor same goes for the next but with a plus sign
