If A is a symmetric matrix , then `A^(3)` is a ........ Matrix.

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

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

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

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

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

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

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

It A is a symmetric matrix, write whether A^T is symmetric or skew - symmetric matrix.

If A=[(1,5),(6,7)] , verify that A+A' is a symmetric matrix and A-A' is a skew-symmetric matrix.
