🔍 Key Concepts

• SI metric prefixes and their powers of ten • Relationship between "micro" and more familiar prefixes like "milli" and "nano" • How many zeros are in thousandth, millionth, billionth, trillionth

💭 Think About

• Start from a prefix you know well, like milli- (thousandth), and recall whether micro- is larger or smaller than that. • Compare micro- to nano- and think: which one is used for very tiny electronic components, like nanoseconds or nanometers? • Translate each choice into a fraction (e.g., 10^-3 = 1/1000) and picture how small that actually is.

✅ Before You Answer

• Be sure you remember that milli- (m) is 10^-3 and kilo- (k) is 10^3, then place micro- (µ) relative to milli. • Double-check that millionth means 1 divided by 1,000,000 and match that to the correct power of ten. • Confirm that you are matching the prefix to both the size word (thousandth, millionth, etc.) and the power of ten (10 to the ?).
