Let A=[(1,1,1),(1,-1,0),(0,1,-1)], A_(1) be a matrix formed by the cofactors of the elements of the matrix A and A_(2) be a matrix formed by the cofactors of the elements of matrix A_(1) . Similarly, If A_(10) be a matrrix formed by the cofactors of the elements of matrix A_(9) , then the value of |A_(10)| is
