If `A=[[-2,1],[-5,4]]` then the Eigen values of of B, where B=`3A^(-1)+3A+2I` ,is

If A={1,2,3,4}, B={5,6} then the value of A cup B is

The eigen value of A=[[1,-42,-3]] are

If ([3,27,5])A([-1,1-2,1])=([2,-10,4]) then sum of the eigen values of A

If A = [(-1,2),(3,1)],B=[(1,0),(-1,0)] then the value of 2A+B+2I=

If A=([1,2],[-3,4]) ; B=([3,1],[2,5]) , then find the value of A+B .

1) If A=[(1,2),(3,4)] , AdjA=[(4,a),(-3,b)] then the values of a and b are ..... a) a=-2, b=1 b) a=2, b=4 c)a=2, b=-1 d) a=1, b=-2

If A={1,2,3,4,5} and B={1,3,5,7,9} then find the value of (A-B)uu(B-A)

Let A=[[2,4],[-1,-2]] ,then the value of det(1+2A+3A^(2)+4A^(3)+5A^(4)+...+101A^(100)) equals (where I is the identity matrix of order 2)
