How do you write 30000000 in scientific notation?

To get to “standard” scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, 3,000,000 becomes 3.000,000 . The trailing zeroes are not significant, so 3.000,000 becomes 3 . We moved the decimal point six places, so the exponent is 6 .

Why do we convert numbers to scientific notation?

The primary reason for converting numbers into scientific notation is to make calculations with unusually large or small numbers less cumbersome. Because zeros are no longer used to set the decimal point, all of the digits in a number in scientific notation are significant, as shown by the following examples.
