A and B are two given matrices such that the order of A is `3 xx 4` if A'Band BA' are both defined then

Let A and B be two matrices such that the order of A is 5xx7 . If A^(T)B and BA^(T) are both defined, then (where A^(T) is the transpose of matrix A)

Let A and B be two matrices such that the order of A is 5xx7 . If A^(T)B and BA^(T) are both defined, then (where A^(T) is the transpose of matrix A)

If A and B are 3times3 matrices such that AB=A and BA=B, then

If A and B are two square matrices of the same order, then AB=BA .

If A and B are two matrices such that both A+B and AB are defined, then

If A and B are two matrices such that Aand AB are both defined,then

If A and B are two matrices such that AB and A+B are both defined, then A and B are

If A and B are symmetric matrices of same order, then AB-BA is

If A and B are two matrices such that A+B and AB are both defined, then
