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.

Let A=[a_(ij)] is a square matrix of order 2 where a_(ij)=i^(2)-j^(2) . Then A is (i) Skew - symmetric matrix (ii) Symmetric matrix (iii) Diagonal matrix (iv) None of these
