To determine whether zeros are considered significant digits based on their placement in a number, let's examine the specific cases mentioned in the question.
### Understanding Significant Figures:
1. Zeros Between Non-zero Digits: Any zero that appears between non-zero digits is always considered significant.
- For example, in the number 13.04, the zero is between the digits 3 and 4, so it is considered significant.
2. Trailing Zeros After a Decimal Point: Zeros that appear to the right of the decimal point and at the end of a number are also considered significant.
- For example, in the number 13.0400, the zeros following the 4 are significant because they determine the precision of the measurement.
### Application:
Given the example number 13.04, we observe the following:
- 13.04: The number 13.04 has a zero between the decimal point and another digit (4). Therefore, this zero is significant.
Based on these rules, the statement, "Zeros are always considered significant digits when they are to the right of the decimal point and when they are between the decimal point and another digit," is accurate.
Thus, the correct answer is:
A. True
