+Given a natural radicand, return its square root.
+
+Note that the term "radicand" refers to the number for which the root is to be determined. That is, it is the number under the root symbol.
+
+Check out the Wikipedia pages on [square root](https://en.wikipedia.org/wiki/Square_root) and [methods of computing square roots](https://en.wikipedia.org/wiki/Methods_of_computing_square_roots).
+
+Recall also that natural numbers are positive real whole numbers (i.e. 1, 2, 3 and up).
