If A = `[[2,2],[4,0]]` and B = `[[1,1],[2,1]]`, then:
`(a)abs(A)=2^3abs(B)`

`(c)abs(A)=abs(B)`
`(d)abs(A)=2^4abs(B)`

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

If A= [[2,4,-1],[-1,0,2]], B=[[3,4],[-1,2],[2,1]] , Show that (AB)'=B'A' .

If abs(a)=1, abs(b)=2" and "abs(a-2b)=4" then "abs(a+3b) is equal to

if A=[{:(0),(1),(2):}]and B=[3" "2" "1], then show that : (AB)'=B'A'
