Find AB, if `A=[0-1 0 2]`and `B=[3 5 0 0]`.

Find AB, if A=[[0,-10,2]] and B=[[3,50,0]]

Show that A B!=B A in each of the following cases: A=[5-1 6 7] and B=[2 1 3 4] (ii) A=[-1 1 0 0-1 1 2 3 4] and B=[1 2 3 0 1 0 1 1 0] (iii) A=[1 3 0 1 1 0 4 1 0] and B=[0 1 0 1 0 0 0 5 1]

If A=[[0,-1],[0,2]] and B=[[3,5],[0,0]], then find A.B and B.A

Find AB if A = [{:( 2,1,3),( 2, 9, 2 ),( 7, 4 , 3):}] and B = [{:( 1, 0 , 0),( 0,0,1),(0, 1, 0):}]

Find AB and BA if exists from the following matrices A and B: (i) A=[{:(2,3,-1),(0,1,2):}]and B=[{:(2,-6),(-4,0):}] (ii) A=[{:(1,2,3),(0,1,-2),(-1,0,-1):}]and B=[{:(0,0,2),(2,0,0),(0,2,0):}] (iii) A=[{:(0,3,4),(2,1,-2),(1,-3,-1):}]and B=[{:(2,1,3),(-1,0,-2):}]

If A = [ (1) , (2), (3)] and B = [ (3, 0, -2)] , find AB .

if A=[[2,5],[0,0]] and B=[[5,0],[-2,0]] then AB=...

If A=[(0,2),(0,3)] and B =[(2,5),(0,0)] then AB =[(0,0),(0,0)]

" 5."[" If "A=[[3,4,2],[1,0,6]]" and "B=[[2,3,0],[1,0,4]]],[" then find "3A-2B]

Find the angles made by the line AB with the positive directions of the coordinate axes, if A is (0,sqrt3,0) and B is (0,0,-1).
