  Listen, okay, for some reason, all of these kinda just merge into the
  same category in my head. Do they all do the same thing? No, not really.
  Does that make a difference to me? No. No, it does not.

  Have you ever seen 3blue1brown's video on the power triange? It's
  an interesting way of thinking about how logarithms, exponentials,
  and roots all relate to each other. Anyhoo, these all relate to that.
