WebIn order for a sub set of R 3 to be a sub space of R 3, both closure properties (1) and (2) must be satisfied. However, note that while u = (1, 1, 1) and v = (2, 4, 8) are both in B, their sum, (3, 5, 9), clearly is not. Since B is not closed under addition, B is not a subspace of R 3. Example 3: Is the following set a subspace of R4?
