Prove that two finite dimensional vector spaces V1 and V2 over R are isomorphic if and only if dim V1 = dim V2. [Hint: use bases to define an isomorphism, then explain why it works.]
Added by Michael B.
Step 1
Two vector spaces V1 and V2 are said to be isomorphic if there exists a bijective linear map (also known as an isomorphism) between them. This means that every vector in V1 can be uniquely associated with a vector in V2 and vice versa, and the operations of vector Show more…
