If A = egin{bmatrix} 1 & 2 & 0 \ 1 & 4 & 4 \ -1 & 3 & -4 end{bmatrix} and B = egin{bmatrix} 4 & -1 & -3 \ -4 & 1 & 1 \ 4 & -1 & -2 end{bmatrix}, then AB = egin{bmatrix} Box & Box & Box \ Box & Box & Box \ Box & Box & Box end{bmatrix} and BA = egin{bmatrix} Box & Box & Box \ Box & Box & Box \ Box & Box & Box end{bmatrix} Choose True or False: AB = BA for any two square matrices A and B of the same size.

If A = and B = then AB = and BA = True or False: AB = BA for any two square matrices A and B of the same size.
Sarin S.
If A = [[-2, 1, 4], [3, -1, -3], [2, -2, -3]] and B = [[-4, 4, -1], [1, -1, -3], [-2, 3, 1]], then AB = and BA = True or False: AB = BA for any two square matrices A and B of the same size. False
Sri K.
If AB + BA is defined, then A and B are square matrices of the same size. True False
