Final answer:
The power of 10 for the prefix 'nano' is -9, meaning it's equivalent to 1 x 10⁻⁹ meters in scientific notation.
Step-by-step explanation:
The power of 10 associated with the prefix "nano" (n) is -9. In scientific notation, this means that one nanometer is 1 x 10⁻⁹meters. Scientific notation is a way to express numbers as a product of a coefficient and a power of 10. The base number for scientific notation is always 10. A nano measurement, such as a nanometer, represents one billionth of a meter, considering that a nano prefix indicates 10⁻⁹.
To understand this in the context of scientific notation, it's helpful to also grasp how such notation works with other numbers. For example, the number 56,900 can be expressed as 5.69 × 10⁴ and 0.000028 can be represented as 2.8 × 10⁻⁵.
