Interpretation: The correct number of significant figure has to be given.
Concept introduction:
Scientific notation expression: A number is expressed as the product of two numbers:
Significant of zeroes:
- Zeroes between two other significant digits are significant.
- Zeroes to the right of a nonzero number, and also to the right of decimal place, are significant.
- Zeroes that are placeholders are not significant.
