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

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

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

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

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

If A=[(-1,0,2),(3,1,4)], B=[(0,-2,5),(1,-3,1)] and C=[(1,-5,2),(6,0,-4)], then find (2A-3B+4C).

(a) If A=[[3,-2],[1,6]] and B=[[4,-1],[2,5]] find AB

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

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

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.

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