In the metric system, metric prefixes are based on powers of which number?

• A. 5
• B. 10
• C. 100
• D. 2

Answer: (B)

Verified step by step guidance

1. Understand that metric prefixes are used to denote multiples or fractions of units in the metric system.
2. Recall that the metric system is based on powers of 10, which makes conversions straightforward by shifting the decimal point.
3. Recognize common metric prefixes such as kilo- (10^3), centi- (10^-2), and milli- (10^-3), all of which are powers of 10.
4. Note that other numbers like 2, 5, or 100 are not the basis for metric prefixes, even though 100 is a power of 10 squared, the system fundamentally relies on 10 as the base.
5. Conclude that the metric prefixes are based on powers of 10.
