Dear Smart people,
I desparately need someones help with this. I have only a few days til my exam.
Please dont give me a hint.
Please give a full explanation.
Suppose that {u1, u2, u3} is a basis for a vector space V , and that W is a subspace of V .
Is it always true that some subset of {u1, u2, u3} is a basis for W? Explain..
Thankyyou
