" If "A=[[2,-3,-5],[-1,4,5],[1,-3,-4]]" and "B=[[-1,3,5],[1,-3,-5],[-1,3,5]]" then find AB."

If A={:[(2,-3,-5),(-1,4,5),(1,-3,-4)]:} and B={:[(-1,3,5),(1,-3,-5),(-1,3,5)]:} show that AB = BA = 0, where 0 is the zero matrix of order 3xx3 .

If A=[[3,3,5],[4,4,4]] and B=[[1,3],[-1,2],[0,0]] then find AB

If A=[[1,2],[-3,4]] and B=[[5],[-1]] then find AB

If A=[(2 ,-3, -5), (-1, 4, 5),( 1, -3 ,-4)] and B=[(-1, 3, 5), (1,-3, -5) , (-1, 3, 5)] , show that A B=B A=O_3xx3 .

If A=[[1,3,5],[-2,5,7]] and 2A-3B=[[4,5,-9],[1,2,3]], find B

Given A= [[5,0,4],[2,3,2],[1,2,1]] , B^-1 = [[1,3,3],[1,4,3],[1,3,4]] ,find (AB)^-1 .

If A = [[1,-2,3],[-4,2,5]] and B = [[2,3],[4,5],[2,1]] , then find AB, BA. Show that AB ne BA

If A=[[1,-2, 3,],[ 4, 2, 5,]] and B=[[2, 4], [2,3],[ 5, 1]] , then find AB, BA. Show that A B!=B A .

If A=[[1 ,-2 , 3],[ -4, 2 ,5]] and B=[[2 , 3],[ 4, 5], [2 , 1]] , then find A B, B A . Show that AB ne BA .
