Question

1. What do you mean by radix of a number system?

Answer 1

The decimal number system that we use every day has 10 digits {0,1,2,3,4,5,6,7,8,9} and so the radix is 10 (also called Base 10).
• Binary digits can only be 0 or 1, so the radix is 2 (or Base 2).


"Radix" can also mean the number that is going to be raised to a power.

Example: in 82, 8 is the radix (or, more commonly, the base)

Answer 2

Answer:

In a positional numeral system, the radix or base is the number of unique digits, including the digit zero, used to represent numbers. For example, for the decimal/denary system (the most common system in use today) the radix (base number) is ten, because it uses the ten digits from 0 through 9.
