Linear Indepedence

  1. Oct 22, 2009 #1
    1. The problem statement, all variables and given/known data

    Suppose B and A are a basis in vector space V, dimension N, now if I can any linear independent columns of basis B and A can I combine them to make a new basis C provided that all the all, even the unused vectors of bases A & B linear combinations of C.

    2. Relevant equations



    3. The attempt at a solution
    I guess the key thing to do here would be to look at the null space of C and see how it compares to A, if this is a problem in R^n then if the null spaces where the same then so would be the basis. So I guess I am just looking for a general method of figuring out if the span of two column spaces are the same, is the question posed true or false?

    Huh? There seem to be some words missing. Please provide the exact problem description.
