(a)
Interpretation: The significant zeros needs to be determined.
Concept Introduction: Measurement lies at the heart of doing science. Any measurement involves an estimate and thus is uncertain to some extent. A reliably identified digits used to find a decimal point is known as significant figure.
(a)

Answer to Problem 3RQ
The answer is
Explanation of Solution
The number of meaningful digits in a calculated quantity is known as significant figures. All non- zero digits are significant and leading zeros are never count as significant but captive zeros are significant.
The given number is
(b)
Interpretation: The significant zeros needs to be determined.
