$\\ e = \sum\limits_{i = 1}^{ \infty} \bigg[ \frac{n}{5^{i} } \bigg] < \sum\limits_{i = 1}^{ \infty} \bigg( \frac{n}{5^{i} } \bigg)$

$\\ e = \sum\limits_{i = 1}^{ \infty} \bigg[ \frac{1}{5^{1}} + \frac{2}{ {5}^{2}} + \frac{3}{ {5}^{3} } + ... \bigg] \\ \quad \ < \sum\limits_{i = 1}^{ \infty} \bigg( \frac{1}{5^{1} } + \frac{2}{ {5}^{2} } + \frac{3}{ {5}^{3} } + ... \bigg)$
