Find the rank of matrix.A= [[3,1,2,0],[1,0,-1,0],[2,1,3,0]]

If A=[[1,0],[0,1]],B=[[1,0],[0,-1]] and C=[[0,1],[1,0]] then show that A^(2)=B^(2)=C^(2)

If A=[[0,1],[1,0]] , then A^2 is equal to: (a) [[0,1],[1,0]] (b) [[1,0],[0,1]] (c) [[1,0],[1,0]] (d) [[0,0],[1,1]]

If A=[[x,1],[1,0]] and A^2=I , then A^(-1) is equal to: a) [[0,1],[1,0]] b) [[1,0],[0,1]] c) [[1,1],[1,1]] d) [[0,0],[0,0]]

Find the adjoint of the following matrices: A = [(1,-1,1),(2,3,0),(18,2,10)]

If [[2" "1" "3][{:(-1,0,-1),(-1,1,0),(0,0,1):}]*[{:(1),(0),(-1):}]=A find A.

[(1,3,-2),(-3,0,-5),(2,5,0)] =A [(1,0,0),(0,1,0),(0,0,1)] then, C_(2) rarr C_(2)-3C_(1) and C_(3) rarr C_(3) +2C_(1) gives... [(1,0,0),(3,-9,11),(-2,1,4)] =A [(-1,3,2),(0,-1,0),(0,0,-1)] [(1,0,0),(-3,-1,-4),(2,-9,11)] =A [(1,-3,2),(0,1,0),(0,0,1)] [(1,0,0),(-3,1,4),(-2,9,-11)] =A [(-1,3,2),(0,-1,0),(0,0,-1)] [(1,0,0),(-3,9,-11),(2,-1,4)] =A [(1,-3,2),(0,1,0),(0,0,1)]

If A = [[x,1,-x],[0,1,-1],[x,0,7]] and det (A) = |(3,0,1),(2,-1,0),(0,6,7)| , then the value of x is a)-3 b)3 c)2 d)-8

Let f(x)=x^2-5x+6 . Find f(A), if A=[[2,0,1],[2,1,3],[1,-1,0]]
