Asked by muskan | 15 May, 2012, 05:16: PM
Expert Answer
In a number, if there are x no. of significant digits, then first (x-1) digits are reliable or certain digits and the last digit which is the estimated one is the uncertain digit.
For eg., if a distance is measured to be 738.4 m, it has four significant digits. The digits 7, 3 and 8 are reliable or certain, while the digit 4 is uncertain.
