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

2) If A=[(1,2),(5,7)],B=[(2,1),(3,4)] , find AB.

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

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

If A=[[1,2,3]], B=[(-5,4,0),(0,2,-1),(1,-3,2)] then (A) AB=[(-2),(-1),(4)] (B) AB=[-2,-1,4] (C) AB=[4,-1,2] (D) AB=[(-5,4,0),(0,4,-2),(3,-9,6)]

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

If A={:[(1,7),(5,6)]:},B={:[(-3,2),(-1,5)]:}andC={:[(2,-3),(4,1)]:} , then find A(B+C) and AB+AC.

If A=[{:(,2,-1),(,3,4):}]=B=[{:(,5,2),(,7,4):}],C=[{:(,2,5),(,3,8):}] and AB-CD=0 find D.

A=[(3,4),(4,5)],B=[(5,3),(2,1)] then AB is ? .

If A = [(1,2),(3,-2),(-1,0)]and B = [(1,3,2),(4,-1,3)] then find the order of AB.
