Concept:The radix, or base, of a number system is the total number of unique digits it uses to represent numbers.
Explanation:The hexadecimal number system uses 16 distinct symbols:
0 to
9 and
A to
F.
The letters
A to
F represent the values
10 to
15.
Since there are 16 unique symbols, its radix is
16.
In hexadecimal, each digit position represents a power of
16.
For example,
2F16=(2×16)+(15×1).
This base is commonly used in computing because it translates easily to binary, with one hexadecimal digit equal to four binary bits.
Answer:The radix of the hexadecimal number system is
16.
Correct option: C. 16
