If m is countable, it means that there exists a one-to-one correspondence between the set of natural numbers and the set of elements in m. Therefore, for each element in m, there is a unique natural number that can be associated with it. When we consider the Cartesian product m x m, we can create a mapping that pairs each element in m with another element in m, forming an ordered pair. Since there is a one-to-one correspondence between the elements of m and the natural numbers, we can create a similar one-to-one correspondence between the elements of m x m and the natural numbers, making m x m countable. **
