Rule for Multiplication - When you multiply numbers with scientific notation, multiply the coefficients together and add the exponents. The base will remain 10. Rule for Division - When dividing with scientific notation, divide the coefficients and subtract the exponents. The base will remain 10. 1) (6.8 x 103) x (4.54 x 106) 2) (2.0 x 10-1) x (8.5 x 105)

because they are exact numbers. Any such equality will not dictate the sig figs in your final answer. G. More examples: 1. 3340 x 1.2 = 4.0 x 103 The answer must have 2 sig dig cause of the 1.2 thus 4000 is incorrect because it only has 1 sig dig. 2. 88359 / 3 = 30000 The answer can only have 1 sig dig cause of the 3. 3.
