| http://www.w3.org/ns/prov#value | - We know there must be a real solution for x (the graph of any odd-degree polynomial goes off to infinity in different directions and hence must cross the x-axis at least once), and the solution is approximately 0.632835??? but it turns out there is no better way to write the solution for x other than to write an approximation to as many decimal places as you want.
