If `A=[(2),(7),(8)] B=[(-3,4,1)]` find `(AB)'`

2) If A=[(1,2),(5,7)],B=[(2,1),(3,4)] , 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 = [(-1),(2),(3)] and B = [(2,0,-4)] , then find AB .

Find the inverse of each of the matrices given below : If A=[(3,2),(7,5)] and B=[(6,7),(8,9)], " verify that " (AB)^(-1)= B^(-1) A^(-1) .

Given A={:[(2,-3),(4,5)]:},B={:[(7,9),(8,1)]:}andC={:[(-2,3),(1,-5)]:} , find (AB)C and A(BC). What do you notice ?

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

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

If A=[{:(2,-3,1),(0," "7,-9):}]" and "B=[{:(1,2,-3),(4,8,-4):}]," find "(A-B)

If A= [{:(,1,2),(,3,-4),(,5,6):}]and B=[{:(,4,5,6),(,7,-8,2):}] will AB be equal to BA. Also find AB & BA.
