For example 0.00017 has 2 significant figures; therefore the correct scientific notation for this number would be \(1.7 10^{-4}\). . For example: log (210^5) = 5.301029995663981 - you should round this figure to 5.3. Trailing zeros are zeros after non-zero numbers. You can never have exactly the exact measurements that you need. The resulting answer would be 4.70 which has 3 significant figures. In significant figures counter mode it will count the number of significant digits in a number. For example, if the sample size is 150, the log of 150 is approximately 2.18, so we use 2 significant figures. Following the rules for doing multiplication and division with significant figures you should round your final answer to the fewest number of significant figures given your original numbers. How many significant figures are there in? For a very small number such as 6.674 x 10 the E notation representation is 6.674E-11 (or 6.674e-11). There are a lot of rules regarding the figures. For example, a weight of 22 g has two significant digits. To practice identifying significant figures in numbers see our for use in every day domestic and commercial use!
