1 7-4 Scientific Notation Goals:
Use scientific notation to represent numbers. Multiply and divide numbers in scientific notation. Eligible Content: A

2 Vocabulary Decimal Form – regular numbers.
Examples: 75,000,000 0.0045 230 Scientific Notation – a shorter way to write really big or really small numbers. 6.02 x 105 9.2 x 10-5

3 Scientific Notation Always looks like:
c can be any number from 1 to 10, but it cannot be 10. 1 ≤ c < 10 n can be any integer (positive or negative whole number). If n is positive, the number is larger than 1. (big numbers) If n is negative, the number is smaller than 1. (small numbers)

4 Examples Write each number in scientific notation. 2.4 x 107
24,000,000 36,400 0.002 4,502,000,000 2.4 x 107 3.64 x 104 3.5 x 10-4 2 x 10-3 4.502 x 109
