If `A=[(4,1),(2,3)] and B=[(3,2),(5,1),(3,5)].` Find `AB' and BA.`

If A=[(1,-2,3),(-4,2,5)] and B=[(2,3),(4,5),(2,1)] , find AB and BA and show that AB!=BA

If A=[{:(5,4),(2,3):}]" and "B=[{:(3,5,1),(6,8,4):}] , find AB and BA whichever exists.

If A=[(2,-3,1),(-2,3,4)] and B=[(2,5),(3,1),(4,2)] , then Find AB

Let A=[{:(1,-2,3),(-4,2,5):}]" and "B=[{:(2,3),(4,5),(-2,1):}]. Find AB and BA, and show that ABneBA.

If A=[(1,-1,1),(1,-2,-2),(2,1,3)] and B=[(-4,4,4),(-7,1,3),(5,-3,-1)] Find AB and hence find the solution of the following system of linear equations.

Let A=[(1,2,3),(2,3,4),(-1,1,2)] and B=[(0,2,-1),(0,3,4),(0,-2,-3)] Find AB and BA ?

if A=[{:(1,2,3),(4,5,6):}]and B=[{:(-3,-2),(0,1),(-4,-5):}], then find AB and BA ,

if A=[{:(4,0,-3),(1,2,0):}]and B=[{:(2,1),(1,-2),(3,4):}]' then find AB and BA.

Let A=[(2,4),(1,-3)] and B=[(1,-1,5),(0,2,6)] (a) Find AB. (b) Is BA defined ? Justify your answer.

If A = [ ( 2,-1,1),(2,-3,5) ] , B = [(3,-3),(4,-1),(5,0)] , find AB.
