If `U=["2 -3 4"],V=[(3),(2),(1)],X=["0 2 3"]andY=[(2),(2),(4)]`, then find `UV+XY`

If U=[2 -3 4], V=[(3),(2),(1)] X=[0 2 3], Y=[(2),(2),(4)] then find UV,XY,UV+XY.

U=[2" "-3" "4],V=[{:(3),(2),(1):}] X=[0" "2" "3]and Y=[{:(2),(2),(4):}] then UV +XY=……….

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

Find x, y if 3[(4,2),(1,3)] - 2[(-2,1),(3,2)] + [(x , - 4),(3,y)] = 0

A={:[(-5,-3,4),(3,2,-4)]:}andB={:[(-4,5,-2),(3,1,5)]:} , then find X such that 3A-2B+X=0.

If A=[{:(3,-2),(4,-2):}]andI=[{:(1,0),(0,1):}] , find k so that A^(2)=kA-2I .

If A=[[2,3,4],[-3,0,2]], B=[[3,-4,-5],[1,2,1]] and C=[[5,-1,2],[7,0,3]] , find the matrix X such that 2A+3B=X+C
