today I have a problem which I see in book Abstract Algebra of David. This is problem:

Let $F$ be a finite field of order q and let $f(x)$ be a polynomial in $F(x)$ of degree $n\geq 1$. Prove that $F[x]/\langle f(x) \rangle$ has $q^n$ elements.

    I am having second thoughts about whether this is a close enough duplicate of [this one](http://math.stackexchange.com/q/239078/11619). All potential "close"-voters, please form your opinion without trusting mine. Sorry about being a tad trigger happy today.2012-11-20
