It looks like you have an incomplete expression: "3 * 4 [BLANK] 5". The blank likely represents an unknown operation, such as addition (+), subtraction (-), multiplication (*), division (/), or other operators.

Here are a few possible interpretations:
1. **Addition:** \( 3 * 4 + 5 = 12 + 5 = 17 \)
2. **Subtraction:** \( 3 * 4 - 5 = 12 - 5 = 7 \)
3. **Multiplication:** \( 3 * 4 * 5 = 12 * 5 = 60 \)
4. **Division:** \( 3 * 4 / 5 = 12 / 5 = 2.4 \)
5. **Exponentiation:** \( 3 * 4^5 = 3 * 1024 = 3072 \)

Please let me know which operation you'd like to fill in or if you have another in mind!
