If `A=[(1,-2,3),(4,5,-1),(5,0,2)]` find `3A`

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

Given A=[(1,2,-3),(5,0,2),(1,-1,1)] and b=[(3,-1,2),(4,2,5),(2,0,3)] , find the matrix C such that A+C=B .

If A=[(1,0),(3,-1),(-5,2)] and B=[(1,-2),(-2,2),(1,1)] , then find the matrix 'X' such that 3A + X = 5B.

If A=[(1,-2,3),(-4,2,5)] and B=[(2,3),(4,5),(2,1)] , find AB and BA and show that AB!=BA

If A=[(2, 0, 1 ),(2, 1, 3),( 1,-1, 0)] , find A^2-5A+4I and hence find a matrix X such that A^2-5A+4I+X=O .

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

If A=[(1,4),(3,2),(2,5)], B=[(-1,-2),(0,5),(3,1)] , find the matrix D such that A+B-D=0 .

If A=[(2,3,4),(-3,0,2)], B=[(3,-4,-5),(1,2,1)], C=[(5,-1,0),(7,0,3)], then find A+B+C.

If A = [{:(2, 3, -1),(5, 6, 1):}] , then find (0) -A (b) 3A (c) (1)/(4)A .

Let A=[{:(1,-2,3),(-4,2,5):}]" and "B=[{:(2,3),(4,5),(-2,1):}]. Find AB and BA, and show that ABneBA.
