If `A=[[2,0,1],[2,1,3],[1,-1,0]]` find the value of `A^(2)-5A+6I`

If |[x,-6,1],[2x,-3,3],[0,1,2]| =0 find the value of x

If A=[[2,a,-3] , [0,2,5] , [1,1,3]] then,find the value of a for which A^(-1) exists.

Given A=[(4,2,5),(2,0,3),(-1,1,0)] write the value of det. ("2AA"^(-1)) .

If A=[(2, 0, 1 ),(2, 1, 3),( 1,-1, 0)] , find A^2-5A+4I and hence find a matrix X such that A^2-5A+4I+X=O .

Find A^2-5A+6I , if A=[[2, 0, 1],[ 2, 1, 3],[ 1,-1, 0]]

Solve [(1,2),(0,0)] [(x,2),(3,3)]=[(7,0),(1,0)] , and find the value of x.

3.Find the value of (5^0 +4^-1) times 2^2

If A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] find AB and BA.

If a^(2) - 3a -1 =0 , find the value of a^(2) +(1)/(a^(2))

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