Question

How do you write 53657 nanoseconds in scientific notation?

Answer 1

`5.3657 * 10^-5` s.

Explanation:

The scale of prefixes is

• milliseconds = `10^-3` s
• microseconds = `10^-6` s
• nanoseconds = `10^-9` s

so 53657 nanoseconds is

`53657 * 10^-9` s. In general in scientific notation we have only one digit before the dot, so we represent it as

`5.3657 *10^4 * 10^-9` s

`=5.3657 * 10^-5` s.
