Let A= |(a_(1),b_(1),c_(1)),(a_(2),b_(2),c_(2)),(a_(3),b_(3)c_(3))| then the cofactor of a_(31) is:

If, in D={:[(a_(1),b_(1),c_(1)),(a_(2),b_(2),c_(2)),(a_(3),b_(3),c_(3))]:}, the co-factor of a_(r)" is "A_(r), then , c_(1)A_(1)+c_(2)A_(2)+c_(3)A_(3)=

If a, b and c are distinct and D = |(a,b,c),(b,c,a),(c,a,b)|. then the square of the determinant of its cofactors is divisible by

If a, b and c are distinct and D = |(a,b,c),(b,c,a),(c,a,b)|. then the square of the determinant of its cofactors is divisible by

If a, b and c are distinct and D = |(a,b,c),(b,c,a),(c,a,b)|. then the square of the determinant of its cofactors is divisible by
