If A and B are two matrices such that AB = 0, can we deduce that either A or B is a zero matrix? Illustrate by an example.

If A and B are tow matrices such that AB =O, can we deduce that either A or B is a zero matrix ? Illustrate by an example.

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 AB=B and BA=A , then A^2+B^2=

If A and B are two matrices such that AB = A and BA = B then B is equal to__

A and B be 3xx3 matrices such that AB+A+B=0 , then

If A, B are two square matrices such that AB = A and BA = B, then prove that B^(2) = B

If A ne 0 and B ne 0 are two 2xx2 matrices such that AB = 0, then which of the following is correct ?

If A and B be two matrices such that A + B and AB are both defined, show that A and B are both square matrices of the same order.

if A and B are two matrices of order 3xx3 so that AB=A and BA=B then (A+B)^7=

If A and B are two invertible matrices of the same order, then adj (AB) is equal to -
