100.0 G + 0.01 G = 100.01 G Expressed in scientific notation: 1.0001*103 G
The number 1.84 x 103 has three significant figures, 1.84. The 103 part of the number does not count when determining significant figures.
3 significant figures. (The zero after the 5 doesn't count.) 4 significant figures if the zero after the 5 does count. A good way of expressing three thousand four hundred fifty with three, four, or five significant figures is with scientific notation: 3.45 * 103 3.450 * 103 3.4500 * 103
Number =[ ( 4.73 ) ( 103 ) ( 0.568 ) ] + 1.61 = 278
4 significant figures in 4400. A digit within a number is considered significant if: 1. it is a non-zero OR 2. It is a zero that is between two significant figures OR 3. It is a zero at the end of the number To express four thousand four hundred with two significant figures use scientific notation: 4.4 * 103
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
5 of them.
Three of them and they are 103

The number of significant figures depends on the the errors of measurement, the uncertainty of reported values, and the significant figures of table values. Ending zeros are only significant if necessary. For example, suppose I want the number of meters in a kilometer to four significant figures. In scientific notation this would be 1.000 * 103. In regular notation, it would be 1000. The period at the end is not for the end of the sentence, but rather to signify that all included digits represent significant digits with regard to accuracy.
