title: ASCII + Numpad combination for power 10
body: <p>I am writing an app and I need to use power numbers in strings. But I cannot for the life of me figure out how to type power 10 characters. I know that if I hold down <kbd>ALT</kbd> + <kbd>0178</kbd>, the character &quot;²&quot; will appear, but how do I type things like <sup>3</sup> or even <sup>40</sup>?</p>
  <p>I've tried looking online, but only see codes for &quot;²&quot; (and other, non-related ones). I've tried using the Character Map program in Windows but I couldn't find anything in there other than &quot;²&quot;.</p>
