count how many times it would take to move the decimal from its current position to in front of the first digit inside the decimal that is not 0
0.00000000028
1. 0.0000000028
2. 0.000000028
3. 0.00000028
4. 0.0000028
5. 0.000028
6. 0.00028
7. 0.0028
8. 0.028
9. 0.28
10. 2.8
10 times; so take the last number (2.8) and multiply it by 10^-10 (note: when you have a decimal place the coefficcient is negative, and when you have a large number the coefficcient is positive)
2.8 x 10^-10
OR if your using a scientific calculator
2.8E-10

Count the zeros from the decimal to the two and you have.
2.8 x 10 ^(-10)
Because you went a negative 10 places.
