How did you get that? I am confused on that part. How do I express something as a scientific notation?

- pinklion23

count how many decimal spaces there are to find out the power to, and your base number must be less than 10 but more than 1

- anonymous

How do I find the base though?

- pinklion23

here what is your question

- anonymous

You answered it already, but here is a screenshot.

- pinklion23

To write a number in scientific notation: Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.
