6 If a is any nonzero real number and n is a positive integer, then a -n = 1/a n. (Note that a negative exponent is not the same or related to a negative number.)

7 Negative Integral Exponents If a is any nonzero real number and n is a positive integer, then a -n = 1/a n. (Note that a negative exponent is not the same or related to a negative number.)

20 Scientific Notation Examples 5,280 = 5.28 × 10 3.14159 = 1.4159 × 10 -1
21
21 Converting Standard to Scientific 1. Count the number of places (n) that the decimal point must be moved so that it will follow the first nonzero digit of the number. 2. If the original number was larger than 10, use 10 n. 3. If the original number was smaller than 1, use 10 -n.
22
22 Converting Scientific to Standard 1. Determine the number of places to move the decimal point by examining the exponent on the 10. 2. Move to the right for a positive exponent and to the left for a negative exponent.
23
23 Multiplication Example (2,000,000) (0.0000000008) ( 2 × 10 6 ) ( 8 × 10 -10 ) = (2)(8)(10 6 )(10 -10 ) = 16 × 10 -4 = 1.6 × 10 -3 = 0.0016 Scientific Notation is designed for multiplication and division, not addition and subtraction.
