The matrix `[0 5-7-5 0 11 7-11 0]` is (a) a skew-symmetric matrix (b) a symmetric matrix (c) a diagonal matrix (d) an upper triangular matrix

If A is skew-symmetric matrix then A^(2) is a symmetric matrix.

If A is a square matrix,then AA is a (a) skew- symmetric matrix (b) symmetric matrix (c) diagonal matrix (d) none of these

In a skew-symmetric matrix, every principal diagonal element is

The inverse of a skew symmetric matrix is

If A is a skew-symmetric matrix of order 3 ,then the matrix A^(4) is

If A and B are symmetric matrices,then ABA is (a) symmetric matric b) skew-symmetric matrix (c) diagonal matrix (d) scalar matrix

The matrix A=[(1, 0, 0),( 0, 2, 0),( 0, 0, 4)] is (a) identity matrix (b) symmetric matrix (c) skew-symmetric matrix (d) diagonal matrix

If A is a skew-symmetric matrix and n is odd positive integer,then A^(n) is a skew-symmetric matrix a symmetric matrix a diagonal matrix none of these

If A and B are symmetric matrices then AB-BA is a Symmetric Matrix (b) Skewl symmetric matrix Diagonal matrix (d) Null matrix

If A is symmetric as well as skew-symmetric matrix, then A is
