If `A =[{:(1,-1),(1,2):}]and B = [{:(1,0),(1,1):}]`, then what is `B^(-1)A^(-1)` equal to ?

If A =[{:(1,2),(1,1):}]and B = [{:(0,-1),(1,2):}] , then what is B^(-1)A^(-1) equal to ?

If A=[{:(1,2),(1,1):}] and B = [{:(0,-1),(1,2):}] , then what is the value of B^(-1) A^(-1)

If A = a [{:(-1, 0), (-1, 2):}]"nd B "= [{:(3, 2), (-1, 0):}], " then find "B^(-1), A^(-1).

If {:A+B=[(1,0),(1,1)]andA-2B=[(-1,1),(0,-1)]:}," then "A=

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

If A=[{:(0,1),(1,1):}] "and" B=[{:(0,-1),(1,0):}] , then show that (A+B)(A-B)neA^(2)-B^(2)

(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=[{:(alpha,0),(1,1):}]and B=[{:(1,0),(2,1):}] such that A^(2)=B , then what is the value of alpha ?

If A=[(2,2),(-3,2)], B=[(0,-1),(1,0)] then (B^(-1)A^(-1))^(-1) is equal to
