Number =[ ( 4.73 ) ( 103 ) ( 0.568 ) ] + 1.61 = 278 <-----------------------------
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
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.

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)
3633 = 3.6*103
The number 1.89 x 10³ has three significant figures. The digits 1, 8, and 9 are all non-zero digits, which are counted as significant. The scientific notation does not affect the number of significant figures in the coefficient.

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
Three: 3, 9 and 0.
