    Vector Space, Basis

    Let V be an n-dimensional vector space. Let S =
    {v1......vn} be a linearly-independent subset of V consisting of n vectors.
    Show that it is a basis.

    Please either post some of your own work on the problem or explain what you do not understand about the question.
    What does it mean to say that a set of vectors is linearly-independent?

    Im not entirely sure what linearly independent means. But i think for it to be a basis it has to be both linearly independent and be a spanning set. Since we are told that S is linearly independent all thats left to do is prove that L(S) = V but im really not sure where to begin

    Pray tell us how you expect to work a question out not knowing the basic definitions. Do you know any fact about linearly independent sets and the dimension of the v-space?
