If `A=[(1,0),(2,0)] and B=[(0,0),(1,12)]` then= (A) `AB=0, BA=0` (B) `AB=0,BA!=0` (C) `AB!=0,BA=0` (D) `AB!=0,BA!=0`

If A=[(3, 0),(5, 1)] and B=[(-4,2),(1, 0)] Find A^(2)-2AB+B^(2)

If A = [[1,2],[3,0]] and B = [[3,4],[0,6]] , then (AB)^T = ?

if A=[{:(1,0),(0,1):}]and B=[{:(a,c),(b,d):}], then show that (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=[[1,2,3]], B=[(-5,4,0),(0,2,-1),(1,-3,2)] then (A) AB=[(-2),(-1),(4)] (B) AB=[-2,-1,4] (C) AB=[4,-1,2] (D) AB=[(-5,4,0),(0,4,-2),(3,-9,6)]

If A=[(0,0,0,0),(0,0,0,0),(1,0,0,0),(0,1,0,0)] then (A) A^2=I (B) A^2=0 (C) A^3=0 (D) none of these

If A={:[(-2,5),(1,3)]:}andB={:[(6,0),(3,-5)]:} , evaluate AB and BA.

2.If A=[[i,0],[0,-i]] and B=[[0,i],[i,0]], find AB .

2.If A=[[i,0],[0,-i]] and B=[[0,i],[i,0]], find AB .

If A=[{:(0,-1,2),(4,3,-4):}] and B=[{:(4,0),(1,3),(2,6):}] then verify that (i) (A')'=A (ii) (AB)'=B'A'
