Step-by-Step Solution:
Step 1 of 3

Solution 50E: All digits of a measurement including uncertain number are called significant figures. Significant figures = all certain digits + one uncertain digit There are two types of number in scientific work. (i) exact - exactly the values are known when it is measured. The values which are obtained from any measurement is completely certain value (ii) Inexact number- uncertainty in the numbers. The measured values are uncertain. The distance from Grand Rapids, Michigan, to Detroit is listed in a road atlas as 153 miles. Distance is always used to measure by using instrument.So here, distance is not an exact number.

This is called Human...
