1. Decide whether each of the following statements is true or false. If true, explain briefly why, and if false, give an example where the statement fails. (a) (b) If A is a 8 x 6 matrix and its null space has dimension 2, then the columns of A are linearly dependent. If B is a 3 x 3 matrix and its characteristic polynomial is PB(A)=(A-4)(A-6)², (c) then B is not diagonalizable. If M and N are both 3×3 matrices and MN is invertible, then both M and N are invertible.
