21,600 using only four significant figures is still 21,600.
There are 3 significant figures
Significant figures are calculated using various rules.ÊAll non-zero numbers are significant and all zeros that are to the right of the decimal point as well as at the end of a number are significant.ÊTherefore, 1.050L has 4 significant figures.
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.

The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.
The product of 0.05 and 3.1 is 0.16 (rounded to two significant figures). When multiplying numbers with different levels of precision, the result should be rounded to the same number of significant figures as the least precise number, which in this case is 0.05.
Answer: four. All written decimals are significant (even if it is 0).However if you have a physics computation where one number turns out to be x = 2.0 (2 significant figures) and the other turns out to be y = 37.15 (4 significant figures), then to compute the product x*y you should take the least of these significant numbers you are using. Hence, you will find thatx*y = 2.0 * 37.15 (= 74.30) = 74 (rounded to the nearest number with 2 significant digits only.)So, it depends on the context you are using this number in.
86.346 +54.43 9.5 _______ 150.276 Now after we round the number and write it in significant figures , so it should look like this; 150 why? because when we need to round a number using the significant figures , we must look for the smallest significant figures which is 9.5 .
