WebSep 17, 2024 · Let A be a 3 × 3 matrix such that A ( 1 7 0) = A ( 2 0 − 1). Show that the rank of A is at most 2. Solution If we set b = A ( 1 7 0) = A ( 2 0 − 1), then A x = b has multiple solutions, so it does not satisfy condition 6 of the Theorem 3.6. 1. Therefore, it does not satisfy condition 5, so the columns of A do not span R 3. WebIn math terms, we say we can multiply an matrix by an matrix . (If happened to be 1, then would be an column vector and we'd be back to the matrix-vector product.) The product is an matrix which we'll call , i.e., .
