Round 5,000.083 to three significant figure.
5,000.083
Since the leftmost digit (5) is to the left of the decimal, we need to keep the 5, and then 2 additional digits, for a total of 3 significant figures.
If we rounded the number off to "5000" as some have suggested, that's only one significant figure.
If we round off to 5000.1 (for example), that's 5 significant figures. In fact, if we keep anything to the right of the decimal point around, we're already expressing at LEAST 5 significant figures.
In this case, we must use scientific notation to ensure that the 0's that we specify are significant, and that we only limit to a total of 3 significant figures.
5,000.083 can be rewritten as :
5,000.083 * 10^0
Which can be rewritten as
5.000083 * 10^3
Now, it's easy to see the express only 3 significant figures!
5.00 * 10^3
500.
5,000.080
Three significant digits:
5, 8, and the 0 after 8
5000.083
5.00×10^3 b/c the number 5.00 has 3 significant figure to simplify this expression we must use scientific notation 5.00 ×10^3 =50000
This means 50000 ~ 5000.083
