title: Xcode Using Exponents
body: <p>This is probably a simple question, but I a variable "side" to be divided by the square of the variable "curNum". Currently, my code for this looks like</p>
  
  <pre><code>side = inputNum/(curNum^2);
  </code></pre>
  
  <p>However, this gives me the error "Invalid operands to binary ^" How can I successfully use exponents?</p>
