1. ## linear algebra

1) The set of all polynomials of degree bigger than or equal n is a vector space.

2.) Let M denote the set of m x n matrices whose entries are rational numbers. M is a vector space over the real numbers( ie. when the set of scalars is the real numbers).

Thank you very much.

there is a checklist of properties you must have to tell whether a set forms a vector space (you can find it here). can you check whether or not your sets satisfy the requirements?

3. Hi Jhvon,

I think the answer of 2) is false. Am i correct?
thanks

2) is false. Just so we know that you know, can you tell us why this is false?
