EXPS 1 | Lesson 3 | Watch (Scientific Notation)

In Explore, when multiplying by powers of 10, the decimal moves either to the right or to the left depending on the sign of the power.

Watch the LearnZillion Video for more information and review on writing large numbers in scientific notation.

LearnZillion: Write large numbers in scientific notation

The video shows how to write large numbers in scientific notation; for example, the distance from the earth to the sun, \(491,000,000,000\) feet, is written as \(4.91\times10^{11}\) in scientific notation. 

Very small numbers can also be written in scientific notation; for example, a micron is \(\dfrac1{1,000,000}\) or \(1\times 10^{-6}\) of a meter. 

In Explore, \(5.47 \times 10^{-2}\) can be written as \(0.0547\), \(3.95 \times 10^{-4}\) can be written as \(0.000395\), and \(0.00324\) can be written as \(3.24 \times 10^{-3}\) using scientific notation.
