If Delta=|(a_(11), a_(12), a_(13) ),(a_(21), a_(22), a_(23)),(a_(31), a_(32), a_(33))| and A_(i j) is cofactors of a_(i j) , then value of Delta is given by (A) a_(11)A_(31)+a_(12)A_(32)+a_(13)A_(33) (B) a_(11)A_(11)+a_(12)A_(21)+a_(13)A_(31) (C) a_(21)A_(11)+a_(22)A_(12)+a_(23)A_(13) (D) a_(11)A_(11)+a_(21)A_(21)+a_(31)A_(31)

If |A| = |(a_(11), a_(12), a_(13)),(a_(21),a_(22),a_(23)),(a_(31),a_(32),a_(33))| = 6 , then write down the value of |A^(-1)| .

If matrix A is [(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)= a) 1/34 b) -2/17 c) 1/17 d) -1/17
