Find `(AB)^(-1) " if "A = {:((1,2,3),(1,-2,-3)):}, B = {:((1,-1),(1,2),(1,-2)):}`

Find AB, if A=[{:(1,2,3),(1,-2,3):}] and B=[{:(1,-1),(1,2),(1,-2):}] . Examine whether (AB)^(-1) exist or not.

if A=[{:(4,3,2),(-1,2,0):}], B=[{:(1,2),(-1,0),(1,-2):}] then |AB| = ……..

A={:[(1,2,1),(3,1,4)]:},B={:[(1,-1),(2,3),(-1,1)]:} , verify (AB)'=B'A'

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

If A^(-1)=[{:(,3,-1,-1),(,1,2,3),(,5,-2,2):}]=[{:(,1,2,-2),(,-1,3,0),(,0,-2,1):}]"find (AB)"^(-1) .

If A^(-1)=|{:(1,3,3),(1,4,3),(1,3,4):}|" and B"=[{:(5,0,4),(2,3,2),(1,2,1):}]," then find"(AB)^(-1)

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

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

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