Answer 2

When writing in standard form, the number must be less than 10.
Then move the decimal point back to where it is less than 10, which is between 5 and 1.
Then count the number of times it is moved, which is 8 times.
The number of times it is moved becomes the exponent.
Therefore, we have
5.1 × 10⁸
