Question

Round 5,000.083 to three significant figure.

Answer 1

5,000.080

Answer 2

Three significant digits:

5, 8, and the 0 after 8

Answer 3

Three significant digits means counting from the left, starting with the first non-zero digit.
Do not add a decimal point unless it is buried in the three significant digits, so
<b>5,00</b>0.080
becomes
5,000

Answer 4

5000.083

Answer 5

500.

Answer 6

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

Answer 7

perform the indicated operations and give answer with the proper number of digit 451 g-15.46g -20.3

Answer 8

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

Answer 9

We need to define with scientific notations so 5.00×10 the power of 3

Answer 10

5.00×103

Answer 11

5.00×10^3
