Concept explainers
(a)
Interpretation:
The total number of significant figures should be identified for the given number.
Concept Introduction:
Significant figures: The term significant figures refer to the number of important single digits in the co-efficient of an expression in scientific notation (for example 0 to 9 inclusive).
In other words precision of measurements, the value recorded should use all the digits known with certainty, plus one additional estimated digit that is usually considered uncertain by plus or minus one it should be written as
The numbers that follow the following rules are considered to be significant.
- 1. All non-zero numbers are significant.
- 2. The zero that present between the two significant digits are also significant.
- 3. The zero that comes after the decimal point is considered as significant.
(b)
Interpretation:
The total number of significant figures should be identified for the given number.
