8.5 Scientific Notation Multiplying and Dividing

Multiplying and Dividing To multiply, divide, or find powers of numbers in scientific notation, use the properties of exponents.

Use the properties of exponents. Example 1: Evaluate Multiply these together. Use the rules of exponents. Not scientific. We will move it to the left once, so we ADD one.

Use the properties of exponents. Example 2: Evaluate Divide these. Use the rules of exponents.

Use the properties of exponents. Example 3: Evaluate Share the exponent.

Use the properties of exponents. Example 4: Evaluate (bottom of p. 471 # 17) In 1994 the population of California was about 3.1 x In that year about 5.6 x local calls were made in California. Estimate the number of local calls made per person in California in 1994.
