Answer:
Make it a new number between 1 and 10
Move the decimal point to make 31830000.0 a new number between 1 and 10. Because our number is greater than 10, we move the decimal point to the left. Drop any trailing zeroes. Keep track of how many times we move the decimal point.
31830000.0 -> 3.183Because our original number was greater than 10, the power of 10 is positive. Remember, we moved the decimal point 7 times, so the exponent is positive 7:
7 over 10
4. Final result 3.183.7 over 10
Our new number is 3.183. We moved the decimal point 7 times.
