                 are defined, you will always know which prime factors belong to the numerator or to the denominator.
                 But I fail to prove this using the direct definition of $f$ like we could do for the natural numbers.
                 This is because the products of the denominators in the last equation are not unique.
                 So maybe I simplified them too much and shouldn't try and write them in terms of $x_1$ and $x_2$ like
                 we did earlier, and try and focus more on just the exponents, but I feel it becomes really hard

             \item[Surjectivity:] We want to show that $f$ is onto, i.e. $f(\{ q > 0 : q \in \Q \}) = \N$.
