Question

1. match the root with the correct definition. pico micro nano giga mega milli

Explanation:

To solve this, we recall the metric prefix definitions:

• pico: $10^{-12}$ (trillionth)
• micro: $10^{-6}$ (millionth)
• nano: $10^{-9}$ (billionth)
• giga: $10^{9}$ (billion)
• mega: $10^{6}$ (million)
• milli: $10^{-3}$ (thousandth)

If we assume the typical definitions (since the problem’s options for definitions aren’t shown, but these are standard):

1. pico → $10^{-12}$ (or "trillionth")
2. micro → $10^{-6}$ (or "millionth")
3. nano → $10^{-9}$ (or "billionth")
4. giga → $10^{9}$ (or "billion")
5. mega → $10^{6}$ (or "million")
6. milli → $10^{-3}$ (or "thousandth")

If the question provides definition options (e.g., "one trillionth", "one millionth", etc.), match each prefix to its corresponding power of 10 or description. For example:

• pico: one trillionth ($10^{-12}$)
• micro: one millionth ($10^{-6}$)
• nano: one billionth ($10^{-9}$)
• giga: one billion ($10^{9}$)
• mega: one million ($10^{6}$)
• milli: one thousandth ($10^{-3}$)

Since the problem’s definition options are not visible, but these are the standard matches for metric prefixes.
