title: How to take square root in c#
body: <p>I have a formula that I want to write in C#. Please find a mistake if any... <img src="https://i.stack.imgur.com/cVLGM.png" alt="Formula Picture">.<br>
  I'm writing in my code same like this:</p>
  
  <pre><code>Xopt = 293.94 * Math.Sqrt(HDD * Cfuel * PWF * K / H4 * Cy * n) - K * Rwt;
  </code></pre>
  
  <p>Unfortunately, the results from this are not the same as the formula. How can I fix it?</p>
