Ireland and Rosen, Exercises 6.2, 6.4, 6.5, 6.6, 6.7, 6.11, 6.12,
6.13, 6.14, 6.18, 6.23, 6.19.

Some of these exercises may be facilitated by invoking or first
establishing the following result: given a nonzero polynomial~$f$ with
rational coefficients, there exists a unique positive rational number
$r$ such that $rf$ has integral coefficients with greatest common
divisor~$1$.
