There should be 3.
When the value 4,449 is rounded to two significant figures the number should be reported as 4,400
Three. At first sight the answer might appear to be 2 but in that case the trailing should not be there. The fact that there is a trailing zero is an indication that the given number is accurate to 3 significant figures.
Three, because if it were not significant, the final 0 should not be there.
Five, because the trailing 0s should not still be there if they were not significant.
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
When performing a logarithmic calculation involving significant figures, the number of significant figures in the result is determined by the number of decimal places in the original values being used in the calculation. The result should be rounded to match the original value with the fewest decimal places.
When dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures in the calculation. Round the final answer to match the least number of significant figures in the original numbers.
There should be 3.
Two sf.
That depends on the context in which it is found, or the calculation(s) involved. It should have no more significant figures than the value with the least number of sig. figs.
Significant figures should be rounded when reporting a measurement or calculation to reflect the precision of the original data. This is done to ensure that the final result is consistent with the accuracy of the measurements used.
To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
When adding numbers with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Add the numbers as usual, then round the result to match the least precise number in the calculation.
significant figures in the original numbers used in the calculation. This means the final answer should be rounded to the same number of significant figures as the number with the least amount of significant figures.
