If `A=[(1, -1), (-1, 1)] and B=[(1, 1), (1, 1)]` then AB=____.

If A=[(1,-1),(-1,1)] and B=[(1,1),(1,1)], prove that AB is null matrix.

(i) if A=[{:(1,0),(0,1):}],B=[{:(0,1),(1,0):}]and C=[{:(1,0),(0,1):}], then show that A^(2)=B^(2)=C^(2)=I_(2). (ii) if A=[{:(1,0),(1,1):}],B=[{:(2,0),(1,1):}]and C=[{:(-1,2),(3,1):}], then show that A(B+C)=AB+AC. (iii) if A=[{:(1,-1),(-1,1):}]and B=[{:(1,1),(1,1):}], then show that AB is a zero matrix.

(i) if A=[{:(1,0),(0,1):}],B=[{:(0,1),(1,0):}]and C=[{:(1,0),(0,1):}], then show that A^(2)=B^(2)=C^(2)=I_(2). (ii) if A=[{:(1,0),(1,1):}],B=[{:(2,0),(1,1):}]and C=[{:(-1,2),(3,1):}], then show that A(B+C)=AB+AC. (iii) if A=[{:(1,-1),(-1,1):}]and B=[{:(1,1),(1,1):}], then show that AB is a zero matrix.

If A=[[1,1] , [0,1]] and B=[[1,-1] , [0,1]] then AB=

If A=[{:(3,-1),(1,-3):}]" and B"=[{:(2,1),(-1,-2):}]," then show that" : (AB)^(-1)=B^(-1)A^(-1)

If A=[{:(3,-1),(1,-3):}]" and B"=[{:(2,1),(-1,-2):}]," then show that" : (AB)^(-1)=B^(-1)A^(-1)

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

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

If A=[{:(2,3),(1,-4):}] and B=[{:(1,-2),(-1,3):}] then verify that (AB)^(-1)=B^(-1)A^(-1)
