How is a quantity expressed in hexadecimal annotated?

• A. Subscript 2
• B. Subscript 8
• C. Subscript 10
• D. Subscript 16

Answer: (D)

A quantity expressed in hexadecimal is annotated using a subscript indicating the base of the numeral system being used. Hexadecimal is a base-16 numbering system, which means it includes digits from 0 to 9 and letters from A to F to represent values ten to fifteen. Therefore, when a value is annotated to specify that it is in hexadecimal form, it is marked with a subscript 16, clearly indicating the base being utilized. In practice, this subscript helps differentiate hexadecimal notation from binary (base 2), octal (base 8), and decimal (base 10) representations. Each of these numeral systems has its own unique notation, and understanding these distinctions is crucial in fields such as computer science and digital electronics, where various bases are commonly used for representing data.
