If `A= (a_(ij))` is a `4xx4` matrix and `C_(ij)`, is the co-factor of the element `a_(ij)`, in `Det (A)`, then the expression `a_11C_11+a_12C_12+a_13C_13+a_14C_14` equals-

In a square matrix the minor M_(ij) and the co-factor A_(ij) of and element a_(ij) are related by

Let A=[a_(ij)]_(nxxn) be a square matrix and let c_(ij) be cofactor of a_(ij) in A. If C=[c_(ij)] , then

Let A=[a_(ij)]_(n xx n) be a square matrix and let c_(ij) be cofactor of a_(ij) in A. If C=[c_(ij)], then

If C_(ij) denotes the cofactor of the elements a_(ij) of the determinant A=|{:(2,-3,5),(6,0,4),(1,5,-7):}| then the value of a_(12)C_(12)+a_(32)C_(32) is :

If C_(ij) is the cofactor of the element a_(ij) of the determinant |{:(2,-3,5),(6,0,4),(1,5,-7):}| , then write the value of a_(32).c_(32)

Choose the correct answer from the bracket.Consider a sqare matrix of order 3.Let C_11,C_12,C_13 are cofactors of the elements a_11,a_12,a_13 respectively,then a_11C_11+a_12C_12+a_13C_13 is

If A=[a_(ij)] is a matrix of order 2xx2 , such that |A|=-15 and c_(ij) represents co-factor of a_(ij) , then find a_(21)c_(21)+a_(22)c_(22) .

Construct a 4xx3 matrix A=[a_(ij)] whose elements a_(ij) are given by: (i) a_(ij)=2i+(i)/(j)
