Question
Chapter L.3, Problem 4RC
Interpretation Introduction
INTERPRETATION:
The product of the given numbers should be determined.
CONCEPT INTRODUCTION:
Significant figures:
The numbers which have meaningful contribution in its measurement are considered to be significant figures.
Certain rules have to be followed for measuring significant figures:
- Non-zero digits are considered to be significant,
- The numbers between two non-zero digits are significant.
- Leading zeros are not significant.
- For a number containing decimal point, zeros right to the last non-zero digits are significant.
- In mathematical operations like addition or subtraction , the significant figures of the result will have the same as that of the number having least number of decimal places.
- In multiplication or division, the result should be rounded to least number of significant digits.
