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, . . ....

Problem 1. Let A be an m x m matrix. (a) Prove by induction that if A is invertible, then for every n N, An is invertible. (b) Prove that if there exists n N such that An is invertible, then A is invertible. (c) Let Ai, . . . , An be m x m matrices. Prove that if the product Ai … An is an invertible matrix, then Ak is invertible for each 1 < k< n. (d)...
