TopNewestThis can be re-arranged to this inequality

\({ \left( 1+\frac { 1 }{ n } \right) }^{ n }\ge 2\displaystyle\prod _{ k }^{ n }{ \frac { k }{ n } } \)

For \(n=1\), we have \(2=2\). Thereafter, the left side approaches \(e\) while the right side drops towards \(0\) – Michael Mendrin · 2 years, 4 months ago
