Solution
Correct Answer:
3
Rules for Significant Figures:
- Leading Zeros: Zeros to the left of the first non-zero digit are not significant. (0.00 are not significant).
- Non-zero digits: Are always significant (3 and 4 are significant).
- Trailing Zeros: Zeros to the right of the decimal point and after a non-zero digit are significant (0 at the end is significant).
- Conclusion: The digits 3,4, and the trailing 0 are significant. Total = 3.
