Query: Evaluating Two Determinants   This article evaluates the determinants of two classes of special matrices,
which are both from a number theory problem. Applications of the evaluated
determinants can be found in [arXiv:math.NT/0509523].
  Note that the two determinants are actually special cases of Theorems 20 and
23 in [arXiv:math.CO/9902004], respectively. Since this paper does not provide
any new results, it will not be published anywhere.
