title: Exponential function with bash, awk or similar
body: <p>I have this text file:</p>
  
  <pre><code>$ cat resultados.txt 
  10.8
  12.1
  14.2
  14.8
  19.4
  8.62
  9.73
  </code></pre>
  
  <p><strong>Important</strong>: numbers are in rows, not in columns.</p>
  
  <p>I want to perform the geometrical operation:</p>
  
  <pre><code>e((l(number1)+l(number2)+l(numbern))/n)
  </code></pre>
  
  <p>How can I do that?</p>
