Show that the following statement is False. "Suppose A and B are two matrices for which the product AB makes sense. If the columns of AB are linearly independent, then the columns of A must be linearly independent and so are the columns of B." Note: You can solve this problem by giving a counter example to the statement above. Note: A and B are not necessarily square matrices. Indeed, for the cases where both A and B are square matrices, we will see later in the semester that the statement will become true.
