title: Logarithm Calculation with Windows 7 Calculator
body: <p>I would like to use the <strong>Windows Calculator</strong> in Scientific Mode in order solve a very basic Logarithm equation but, unfortunately, I couldn't do that.</p>
  
  <p>Here is the problem:</p>
  
  <pre><code>log_5 125=?
  </code></pre>
  
  <p>Thank you very much for your help...</p>
  
  <p>Well, I know it equals to "3", but, how can I use the Windows Calculator to get computed that equation for example?</p>
