Scientific notation is a shorthand for writing either very large numbers or small decimals with lots of digits.
Example:
\(3.69\times 10^{-9}\) means
- First write 3.69
- Move the decimal 9 places left because of \(10^{-9}\). Then fill in the missing places with zeros.
Example:
\(3.69\times 10^{9}\ means
- First write 3.69
- Move the decimal 9 places right because of \(10^{9}\). Then fill in the missing places with zeros.
Example:
\(0.000014\) means \(1.4 \times 10^{-5}\)
- Move the decimal right the given number of necessary places.
- This is 5 places to the right. So the number is \(1.4 \times 10^{-5}\)
Example:
\(36924\) means \(3.6924 \times 10^{4}\)
- Move the decimal left the given number of necessary places.
- This is 4 places to the left. So the number is \(3.6924 \times 10^{4}\)
