  1. So thinking back to our slide triangle, we
    know that 208 is not actually the length
  2. of the slide that we're trying to find.
    Instead, this is the square of that
  3. length. In other words, we want to find
    out which number, when multiplied by
  4. itself, is equal to 208. Is this number
    rational?
