Unformatted text preview: 1 2. If moving the decimal creates any open places, Fll them with zeros. Example 3. 1. 4 . 12 × 10 2 2. 3 . 6 × 10 6 3. 5 . 7 × 103 • Multiplication and Division with ScientiFc Notation: Operate on the powers of 10 (using addition or subtraction according to whether you are multiplying or dividing) and the digit separately. Be sure your Fnal answer is in scientiFc notation. Example 4. 1. (6 × 10 2 )(4 × 10 5 ) = (6 · 4) × (10 2 · 10 5 ) = 24 × 10 7 = 2 . 4 × 10 8 2. 4 . 2 × 102 8 . 4 × 105 = · · · = 5 × 10 2 • Addition and Subtraction with ScientiFc Notation: 1. Write numbers in ordinary notation. 2. Add or subtract. 3. Convert back to ScientiFc notation. Example 5. (3 × 10 6 ) + (5 × 10 2 ) (4 . 6 × 10 9 )(5 × 10 8 ) Remark If both numbers have the same power of 10, you can add or subtract the digit part of the scientiFc notation then convert to scientiFc notation if necessary. Example 6. (7 × 10 10 ) + (4 × 10 10 ) 2...
