A=[a_(ij)]_(m xx n) is a square matrix,if (a)m

Let A=[a_(ij)]_(m×n) is defined by a_(ij)=i+j . Then the sum of all the elements of the matrix is

If a square matrix A=[a_(ij)]_(3 times 3) where a_(ij)=i^(2)-j^(2) , then |A|=

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

Construct a 2 xx 3 matrix A = [a_(ij)]_(2 xx 3) for which a_(ij) = ij

Construct a 2 xx 3 matrix A = [a_(ij)]_(2 xx 3) for which a_(ij) = i - j

Write the element a_12 of the matrix A = [a_(ij)]_(2xx2) a_(ij) = e^(2ix) sin jx .

Construct a 2 x 3 matrix A = [a_(ij)]_(2 xx 3) for which a_(ij) = 2 i + j

If A=[a_(ij)]_(n xx n) and a_(ij)=i(i+j) then trace of A =
