Writing Scientific Notation

Scientific notation is always written using multiplication.

We can move decimals to the right and left by using multiplication only (no need for division) if we're allowed to use positive and negative powers of 10.

 Moving Decimals for Multiplication Only When You By a positive power of 10 By a negative power of 10 X Move the decimal to the right the same number of spaces as the power. Move the decimal to the left the same number of spaces as the power.
 We just learned this. It takes the place of dividing by a positive power of 10

Example 1: Multiply 34.5 x 106

Example 2:
