Find аll TRUE stаtements оut оf fоur following stаtements. (i) If an n × n {"version":"1.1","math":"(n times n)"} matrix A {"version":"1.1","math":"(A)"} is singular, then A is not diagonalizable. (ii) If an n × n matrix A is invertible, then the n {"version":"1.1","math":"(n)"} columns of A are a basis for R n {"version":"1.1","math":"(mathbb{R}^n)"}. (iii) Each eigenvalue of A = [ a b b a ] {"version":"1.1","math":"(, A = left[ begin{array}{ll} a & b \ b & a end{array} right] )"} is a real number for any real numbers a {"version":"1.1","math":"(, a)"} and b {"version":"1.1","math":"(b)"}. (iv) If A {"version":"1.1","math":"(, A , )"} is an n × n orthogonal matrix, then A is nonsingular.
