(d) If `A=[[4,1],[9,0]]` and `B=[[2,0],[7,1]]` then `(A+B)'=`

1. (a) If A=[[2,7],[9,8]]" and "B=[[1,2],[0,3]], then find (A-B)

If A= [[a,b],[c,d]] and I= [[1,0],[0,1]] then A^(2)-(a+d)A=

If A=[[3,9,0],[1,8,-2]] and B=[[4,0,2],[7,1,4]] ,find A+B and A-B .

If =[[1,4,-1],[2,6,5]] and B=[[3,-2,-6],[2,0,-7]] , find A+B and A-B

If A=[[1,4],[0,5],[6,7]] and B=[[2,3,-1],[1,0,-7]] , verify that (AB)\'=B\'A\'

If A=[[-1 ,2, 3],[ 5 ,7, 9],[-2 ,1, 1]] and B=[[-4, 1,-5],[ 1, 2,0 ],[1, 3, 1]] , then (A+B)^(prime)=A^(prime)-B^(prime) is true or false

Q.4 If A= [[0,1,-2],[-1,0,5],[2,5,0]] , then (a)A'=A (b)A'=-A (c)A'=2A (d) None of these

If A+B=[[1,2,1],[1,1,-1],[-3,2,4]] and A-B=[[-2,3,7],[-4,1,0],[2,4,1]] then 2A+4B equals

If A=[[1,2,3]], B=[(-5,4,0),(0,2,-1),(1,-3,2)] then (A) AB=[(-2),(-1),(4)] (B) AB=[-2,-1,4] (C) AB=[4,-1,2] (D) AB=[(-5,4,0),(0,4,-2),(3,-9,6)]
