Countability
... Each rational number ab (written in its lowest terms, so that gcd(a, b) = 1) is represented by the point (a, b) in the infinite two-dimensional grid shown (which corresponds to Z × Z, the set of all pairs of integers). Note that not all points on the grid are valid representations of rationals: e.g. ...

... When the domain of x is extended to the negative real numbers or 0, then the domain of m is limited to those values for which xm is defined. If x m is to be a real number, then the value of x determines the domain for m. (All m statements about x also hold for x n .) Specifically, if x and m are rea ...
