3.If `A=[(1,3,0),(-1,2,1),(0,0,2)]` and `B=[(2,3,4),(1,2,3),(-1,1,2)]` then AB=

If A=[(1,0,0),(0,-1,0),(0,0,2)] and B=[(2,0,0),(0, 3,0),(0,0,-1)] , find A+B , 3A+4B .

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

if A[{:(1,3,-1),(2,2,-1),(3,0,-1):}]and B=[{:(-2,3,-1),(-1,2,-1),(-6,9,-4):}], then show that AB=BA.

If A=[(3,-3,4),(2,-3,4),(0,-1,1)] , then A^(-1)=

Let A+2B=[(1,2,0),(6,-3,3),(-5,3,1)] and 2A-B=[(2,-1,5),(2,-1,6),(0,1,2)], then find tr(A)-tr(B).

Statement 1: A=[(4,0,4),(2,2,2), (1,2,1)] B^(-1)=[(1,3,3),(1,4,3),(1,3,4)] . Then (A B)^(-1) does not exist. Statement 2: Since |A|=0,(A B)^(-1)=B^(-1)A^(-1) is meaning-less.

If A^(-1) =[(3,-1,1),(-15,6,-5),(5,-2,2)] and B = [(1,2,-2), (-1,3,0), (0,-2,1)] find (AB)^(-1)

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

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 A=[{:(1,0,-3),(2,3,4),(-4,5,-2):}]and b=[{:(3,0,-1),(2,5,-4),(4,-1,2):}], then show that : (AB)'=B'A'
