SUMMARY

The discussion centers on the concept of linear independence in vector spaces, specifically regarding the combination of bases A and B to form a new basis C in a vector space V of dimension N. It is established that if linear independent columns from bases A and B are combined, they can indeed create a new basis C, provided that all vectors from A and B can be expressed as linear combinations of C. The key method for verifying this involves examining the null space of C and comparing it to that of A, particularly in the context of R^n.

PREREQUISITES
  • Understanding of vector spaces and their dimensions
  • Knowledge of linear independence and basis concepts
  • Familiarity with null spaces in linear algebra

Homework Statement



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.

Homework Equations





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.
