" If "A=[[3,3,5],[2,3,4],[5,2,3]]" If you show "quad AI_(3)=I_(3)A

If A=[[3,3,52,3,45,2,3]]. Prove that AI_(3)=I_(3)A

If A=[[3,2,01,4,00,0,5]], show that A^(2)-7A+10I_(3)=O

If A= [3,2,0],[1,4,0][0,0,5] , then show that A^2 −7A+10I3 =0

If A=[[1,3],[-2,4]] , then show that , A^2-5A+10I=0

If A = [[3,-5],[-4,2]] ,show that A^2 -5A-14I =0.

If A=[[2/3, 1, 5/3],[ 1/3, 2/3, 4/3] ,[7/3, 2, 2/3]] and B=[[2/3, 3/5, 1],[ 1/5, 2/5, 4/5],[ 7/3, 6/5, 2/5]] , then compute 3A - 5B .

If A=[[2/3, 1,5/3],[1/3, 2/3, 4/3],[7/3, 2, 2/3]] and B=[[2/5, 3/5, 1],[1/5, 2/5, 4/5],[7/5, 6/5, 2/5]] then compute 3A-5B

If A = [[2/3,1,5/3],[1/3,2/3,4/3],[7/3,2,2/3]] and B = [[2/5,3/5,1],[1/5,2/5,4/5],[7/5,6/5,2/5]] , then compute 3A-5B

If A=[(4, 5),( 2 ,1)] , then show that A-3I=2(I+3A^(-1))

if A=[[0,10,0]] then show that (aI+bA)^(3)=a^(3)I+3a^(2)bA
