Abstract

An inequality of H. Minc and L. Sathre (Proc. Edinburgh Math. Soc. ${\bf 14}$(1964/65), 41-46) is generalized as follows: Let $n$ and $m$ be natural numbers, $k$ a nonnegative integer, then we have
$${n+k\over n+m+k}<{{\root n\of {(n+k)!/k!}}\over {\root {n+m}\of {(n+m+k)!/k!}}}<1.$$
From this, some corollaries are deduced. At last, an open problem is proposed.
