Radix

Number Systems: How many digits are used in the number system

Examples:
• 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).


Exponents (Powers): the number that is going to be raised to a power.

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