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

If A=[a_(ij)] is a skew symmetric matrix of order 'n' then suma_(ii)=

If A=[a_(ij)] is a skew-symmetric matrix,then write the value of sum_(i)sum_(j)a_(ij)

If A=[a_(ij)] is a skew-symmetric matrix,then write the value of sum_(i)a_(ij).

If A=[a_(ij)] is a skew-symmetric matrix,then write the value of sum_(i)a_(ii)

If A=[a_(ij)] is a scalar matrix of order nxxn such that a_(ij)=k for all I then |A|=

If A=[a_(ij)] is a square matrix of even order such that a_(ij)=i^(2)-j^(2), then A is a skew- symmetric matrix and |A|=0 (b) A is symmetric matrix and |A| is a square (c) A is symmetric matrix and |A|=0 (d) none of these

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

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

If A=[a_(ij)] is a square matrix of order 3 and A_(ij) denote cofactor of the element a_(ij) in |A| then the value of |A| is given by
