Final answer:
All the given values (12, 64, 1/12, 1/64) represent positive forms since they are all greater than zero. This is true for both positive integers and positive fractions, indicating that all options are technically correct in this context.
Step-by-step explanation:
The question asks which of the following values shows the positive form of an expression. The values given are A. 12, B. 64, C. 1/12, D. 1/64. The expression itself is not provided, but the question seems to revolve around the concept of ensuring an expression is positive, which is generally a matter of looking at the number and determining if it is greater than zero without considering any variables that might be involved.
Given the values listed, all are inherently positive, as they are greater than zero. It is important to note that values A (12) and B (64) are positive integers, whereas values C (1/12) and D (1/64) are positive fractions. In mathematics, any number greater than zero is considered to be in its positive form regardless of whether it is an integer, a fraction, or a decimal. Therefore, without additional context or a specific expression provided, all four options are technically correct answers as they all represent positive values.
