If `A=[(1,0),(0,-1)] and B=[(0,1),(1,0)]`, then `AB=[(0,1),(-1,0)]` .
and `BA=[(0,-1),(1,0)]`. Clearly `AB ne BA`.

Find AB, if A=[(0,-1),(0,2)] and B=[(3,5),(0,0)] .

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

If A=[{:(1,0,0),(0,1,0),(0,0,1):}] then A^(2)+2A = ……….

Given A=[(1,1,1),(2,4,1),(2,3,1)], B=[(2,3),(3,4)]. Find P such that BPA= [(1,0,1),(0,1,0)]

If A=[{:(0,1),(1,1):}]andB=[{:(0,-1),(1,0):}] show that (A+B)*(A-B)neA^(2)-B^(2) .

If A=[{:(-1,2,0),(-1,1,1),(0,1,0):}] then show that A^(-1)=A^2

If A=[{:(1,0,1),(0,1,2),(0,0,4):}] then show that [3A]=27[A]

If A=[{:(0,1),(1,0):}] , then A^(2) is equal to ......

If A=[{:(1,1,-1),(2,0,3),(3,-1,2):}],B=[{:(1,3),(0,2),(-1,4):}]andC=[{:(1,2,3,-4),(2,0,-2,1):}] , find A(BC) , (AB)C and show that (AB) C=A(BC),
