Prove that:
[ x   y     z ] 


Solution: Let us consider the matrices as A , B , C  which are the   so that the matrix ABC will be Evidently they are comfortable for multiplication 
ABC = A(BC)  OR (AB ) C 
(BC) = 
ABC' = A (BC)  n= ]


similarly we can find ABC as (AB)C are AB will be and C being (AB) C will br matrix which will be same as above.
