Explain each step, simple and organize solution Problem 5 (Intersections and unions of subspaces) Let V be a vector space. Let U and W be subspacesof V.1. Show that the intersection UnW is a subspace of V.2. Show that the union UUW is a subspace of V if and only if either UC W or W CU. Hint 1: Try aproof by contradiction. Hint 2: Think about the intersection of two non-parallel planes (passing throughthe origin) in R³ before tackling the general statement.
