1. The problem is to understand if the product $9 \times 8 \times 7 \times 6 \times 5$ can be considered as one expression and if the digit 5 is one of the even digits. 2. First, let's write the product clearly: $$9 \times 8 \times 7 \times 6 \times 5$$ 3. This is a multiplication of five numbers, which can be treated as one expression representing the product of these numbers. 4. Now, let's identify the digits: 9 (odd), 8 (even), 7 (odd), 6 (even), 5 (odd). 5. The digit 5 is not an even digit; it is an odd digit. 6. Therefore, the product can be written as one expression, but 5 is not an even digit. 7. To calculate the product: $$9 \times 8 = 72$$ $$72 \times 7 = 504$$ $$504 \times 6 = 3024$$ $$3024 \times 5 = 15120$$ 8. Final answer: $$9 \times 8 \times 7 \times 6 \times 5 = 15120$$
