The set S={x €Q : x^3 <= 7} where Q = the rationals has supremum = cube root x

But why does it have no maximum?
I though the maximum was also cube root x?

What you are saying makes no sense. The supremum is \sqrt[3]{7} and this is obviously not in \mathbb{Q} so cannot be part of S. Therefore there is no maximum.
