Explain the steps for writing 0.000000001 in scientific notation
To represent a nanometer (nm) in scientific notation, we use the following format: a × 10^b, where 1 ≤ a < 10 and b is an integer.
Since a nanometer is equal to 0.000000001 meter, we can express it as:
1 × 10^-9 meters
Therefore, the expression representing a nanometer in scientific notation is 1 × 10^-9.
