If `{:[(2,-1,0),(9,2,4),(6,3,-9)]:}`, find (k+l) A.

If A = [(3,8,0),(1,6,7),(0,2,-5)] and B = [(-1, 6 ,9),(3,0,4),(2,3,11)] , find 2 A - 3 B.

If [{:(9,-1,4),(-2,1,3),(1,2,-1):}]=A+[{:(1,2,-1),(0,4,9),(3,1,-2):}] , then find the matrix A .

If A=[{:(2,-1,1),(-1,2,-1),(1,-1,2):}] verify that A^(3)-6A^(2)+9A-4I=0 and hence find A^(-1) .

If [(9,-1,4),(-2,1,3)]=A+[(1,2,-1),(0,4,9)], then find the matrix A.

The order of the matrices [{:(1,2,3),(4,5,-1):}], [{:(2,4),(9,2),(6,3),(4,1):}] , [{:(4,5,6),(3,2,1),(9,8,7):}] respectively are :

If A = {0,2,3,5,8} , B = {0,3,6,9,10,12} and C = {2,4,6,8,} find C cup A

Find the matrix A such that : [(1 ,0 ),(0 ,1)]A=[(3 ,3 ,5 ),(1, 0 ,1)] (ii) A[(1, 2, 3 ),(4, 5 ,6)]=[(-7,-8,-9 ),(2, 4 ,6)]
