The number of significant figures in the measurement x = 10.00300 are:
Correct answer: A. 7
- A. 7
- B. 8
- C. 5
- D. 3
Explanation
The number of significant figures in a measurement includes all the certain digits plus the first uncertain digit. In the measurement x = 10.00300, all the digits are significant because:The digits '1' and '0' before the decimal point are significant.The digits '00300' after the decimal point are significant because they follow a non-zero digit.Thus, there are a total of 7 significant figures. Options B, C, and D are incorrect because they either overestimate or underestimate the count of significant figures.
