D
Text Solution
Verified by ExpertsThe correct answer is:
D
To determine the number of significant figures for each of the given numbers, we follow these rules:
Therefore, the respective counts are 5, 1, 2. The correct answer is option D: 5, 1, 2.
- All non-zero digits are always significant.
- Any zeros between significant digits are also significant.
- Leading zeros (those before the first non-zero digit) are not significant.
- Trailing zeros in a decimal number are significant.
- Trailing zeros in a whole number without a decimal point are not significant.
- **23.023**: It has 5 significant figures (all digits are non-zero or significant).
- **0.0003**: It has 1 significant figure (the leading zeros are not counted).
- **2.1 x 10^{-3}**: The coefficient has 2 significant figures (both digits are non-zero).
- First number: 5
- Second number: 1
- Third number: 2
Therefore, the respective counts are 5, 1, 2. The correct answer is option D: 5, 1, 2.
