... To raise a product to a power, raise each factor of the product to that power. To raise a quotient to a power, raise the numerator and the denominator to that power. For any numbers x and y, and any natural number n: (xy)n = xnyn and (x/y)n = xn/yn, where y ≠ 0. ...

... Real numbers and computers A real number is said to be computable if there exists an algorithm that yields its digits. As we shall see later, most real numbers are not computable. Some ‘constructivists’ accept the existence of only those reals that are computable. The set of definable numbers is br ...

CPS311 Lecture: Representing Information in Binary Objectives:
... A. The method we have developed thus far for representing integers in binary only allows us to represent integers >= 0. Obviously, we also need a way to represent negative numbers. B. In decimal, we represent negative numbers by representing their absolute value and preceding it by a negative sign. ...

... Theorem 1: The smallest sequence of twenty consecutive Niven numbers begins with a 101120» mark of digital sum 15830. Proof: Let fi be the first of twenty consecutive Niven numbers and let a = s(j3). Suppose fi has fewer than 1789 digits (i.e., no more than in our example in the previous section). S ...
