If `A=[a_(ij)]` is a square matrix of even order such that `a_(ij)=i^2-j^2`, then

If A = [a_(ij)] is a square matrix of order 2 such that a_(ij) ={(1," when "i ne j),(0," when "i =j):} , then A^(2) is:

If A = [a_(ij)] is a square matrix of order 2 such that a_(ij)={{:(1,"when " i ne j),(0,"when "i = j):} that A^2 is :

If A=[a_(ij)] is a square matrix such that a_(ij)=i^(2)-j^(2), then write whether A is symmetric or skew-symmetric.

If A = [a_(ij)] is a skew-symmetric matrix of order n, then a_(ij)=

Let A=[a_(ij)] be a square matrix of order n such that {:a_(ij)={(0," if i ne j),(i,if i=j):} Statement -2 : The inverse of A is the matrix B=[b_(ij)] such that {:b_(ij)={(0," if i ne j),(1/i,if i=j):} Statement -2 : The inverse of a diagonal matrix is a scalar matrix.

If A is a square matrix for which a_(ij)=i^(2)-j^(2) , then matrix A is

If A=[a_(ij)]_(3xx3) is a scalar matrix such that a_(ij)=5" for all "i=j," then: "|A|=

Given that A = [a_(ij)] is a square matrix of order 3 xx 3 and |A| = - 7 , then the value of sum_(i=1)^3a_(i2)A_(i2) where A_(ij) denotes the cofactor of element a_(ij) is:
