The possible values of scalar k such that the matrix `A^(-1)-kI` is singular where `A = [(1,0,2),(0,2,1),(1,0,0)]`, are

For what value of x, the matrix A is singular? : A=[(x,2,3),(0,2,3),(1,2,3)]

The matrix |(1,0,0),(2,1,0),(3,1,1)| is

If A= [(0,1,1),(0,0,1),(0,0,0)] is a matrix of order 3 then the value of the matrix (I+A)-2A^2(I-A), where I is a unity matrix is equal to (A) [(1,0,0),(1,1,0),(1,1,1)] (B) [(1,-1,-1),(0,1,-1),(0,0,1)] (C) [(1,1,-1),(0,1,1),(0,0,1)] (D) [(0,0,2),(0,0,0),(0,0,0)]

The sum of the values of x so that the matrix ({:(2,2,1),(1,3,1),(1,2,2):}) -x ({:(1,0,0),(0,1,0),(0,0,1):}) is singular, is

Check whether the matrix [(2,1,3),(4,-1,0),(-7,2,1):}] is singular or not

The value of x, so that the matrix A = [(0,1,2),(-1,0,3),(x,-3,0)] is a skew - symmetric matrix is ..........

The sum of the values of x so that the matrix ([2,2,1],[1,3,1],[1,2,2])-x([1,0,0],[0,1,0],[0,0,1]) is singular,is
