If `A` is any `mxxn` such that `A B` and `B A` are both defined show that `B` is an `nxxm` matrix.

If A is any m xx n such that AB and BA are both defined show that B is an n xx m matrix.

If A is any mxxn matrix such that AB and BA are both defined, then B is a matrix of order

If A is an mxxn matrix such that AB and BA are both defined, then B is (A) mxxn matrix (B) nxxn matrix (C) mxxn matrix (D) nxxm matrix

If A is any mxn matrix and B is a matrix such that AB and BA are both defined, then B is a matrix of order

Let A and B are matrices such that A+B and B A are both defined, then

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

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