1. The problem statement, all variables and given/known data A set of 6 vectors in R5 cannot be a basis for R5, true or false? 3. The attempt at a solution I'm thinking true, because any set of 6 vectors in R5 is linearly dependent, even though some sets of 6 vectors in R5 span R5. To be a basis it must be a linearly independent spanning set, so if it's linearly dependent, it cannot be a basis. Am I correct?
