How many Significant digits are in the following?
1) 956044
2) 2.1390
3) 043900
4) 0.00500
5) 3500
7) 0.40001
6) 5.901 x 104
8) 1.0700 x 10-3
9) 7550.
10) 36070000
Round off the following numbers to three significant digits:
11. 120000
14. 4.53619
12. 5.457
15. 63.659
13. 0.0002739
16. 986493
Significant Digits (continued)
Significant figures in derived quantities (Calculations)
In all calculations, the answer must be governed by the least significant figure employed.
ADDITION AND SUBTRACTION: The answer should be rounded off so as to contain the same number of
decimal places as the number with the least number of decimal places. In other words, an answer can be
only as accurate as the number with the least accuracy.
Thus: 11.31 +
33.264 + 4.1 =
48.674
Rounded off to 48.7
MULTIPLICATION AND DIVISION: The answer should be rounded off to contain the same number of
digits as found in the LEAST accurate of the values.
Thus: 5.282 x 3.42 =
18.06444
Rounded off to 18.1
Expert Solution
