If A = [[x,1],[1,0]] and A^2 =I then find the value of x.

If A={:[(0,x),(1,0)]:} , such that A^(2)=4I , then x is

Matrices X and Y are such that 3X + 4Y = I and X-2Y = 2I where I denotes the identity [[1,0,0],[0,1,0],[0,01] matrix . Determine X.

If A= [{:(2, -5), (0, 1):}]" and I" = [{:(1, 0), (0, 1):}] then find the matrix X such that 4A-2X + I = O.

If (A -2I)(A-3I)=0 , when A=[{:(4,2),(-1,x):}] and I=[{:(1,0),(0,1):}] , find the value of x

If sum_(i=1)^(2 n) cos ^(-1) x_(i)=0, then sum_(i=1)^(2 pi) x_(i)=
