let A ={{:({:(a_(11),a_(12)),(a_(21),a_(22)):}):a_(ij){0,1,2} and a_(11)=a_(22)} then the number of singular matrices in set A is

If A=[(a_(11),a_(12)),(a_(21),a_(22))] , then minor of a_(11) (i. e., M_(11)) is

Find the minors and cofactors of the elements of the determinant Delta = |{:(a_(11), a_(12), a_(13)), (a_(21), a_(22), a_(23)), (a_(31), a_(32), a_(33)):}|

If A=[{:(a_(11),a_(12),a_(13)),(a_(21),a_(22),a_(23)),(a_(31),a_(32),a_(33)):}] and A_(ij) is co-factos of a_(ij) , then A is given by :

If A=[{:(a_(11),a_(12),a_(13)),(a_(21),a_(22),a_(23)):}]" and "B=[{:(b_(11),b_(12)),(b_(21),b_(22)),(b_(31),b_(32)):}] then show that AB and BA both exist. Find AB and BA.

,1+a_(1),a_(2),a_(3)a_(1),1+a_(2),a_(3)a_(1),a_(2),1+a_(3)]|=0, then

If A=[[a_(11), a_(12), a_(13)], [a_(21), a_(22), a_(23)], [a_(31), a_(32), a_(33)]] and A_(ij) denote the cofactor of element a_(ij) , then a_(11)A_(21)+a_(12)A_(22)+a_(13)A_(23)=

If A=[[a_(11), a_(12), a_(13)], [a_(21), a_(22), a_(23)], [a_(31), a_(32), a_(33)]] and a_(ij) denote the cofactor of element A_(ij) , then a_(11)A_(11)+a_(12)A_(12)+a_(13)A_(13)=

If matrix [(1,2,-1),(3,4,5),(2,6,7)] and its inverse is denoted by A^(-1)=[(a_(11),a_(12),a_(13)),(a_(21),a_(22),a_(23)),(a_(31),a_(32),a_(33))] value of a_(32)=

If matrix A=[[1, 0, -1], [3, 4, 5], [0, 6, 7]] and its inverse is denoted by A^(-1)=[[a_(11), a_(12), a_(13)], [a_(21), a_(22), a_(23)], [a_(31), a_(32), a_(33)]], then the value of a_(23) =
