In this problem using induction you prove that every finitely generated vector space has a basis. In fact, every vector space has a basis, but the proof of that is beyond the scope of this course Before trying this question, make sure you read the induction notes on Quercus. Let V be a non-zero initely generated vector space (1) Let u, Vi, . . . , v,e V. Prove tfe Span何, . . ....
