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

If A=[(5,-1),(6,7)],B=[(2,1),(3,4)] and C=[(1,3),(-1,4)] , verify the following : (i) (A')'=A (ii) (A+B)'=A'+B' (iii) (3A)'=3A' (iv) (AB)'=B'A' .

Let, A=[(2,4),(3,2)],B=[(1,3),(-2,5)],C[(-2,5),(3,4)] Find AB

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

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

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

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=[(1,-2,0),(2,1,3),(0,-2,1)] and B=[(7,2,-6),(-2,1,-3),(-4,2,5)] , find AB Hence , solve the system of equation x-2y=10, 2x+y+3z=8 and -2y+z=7.

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

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