It seems like you're referring to an expression that involves exponents and possibly needs simplification using the properties of exponents. However, the notation is a bit unclear.
Let's clarify what you're looking for. Based on your description, here's a structured breakdown of what I infer:
- You mentioned -4 a with a small four on top. This typically represents \(-4a^4\).
- There seems to be another term, which is -2 a with a small number on top. It could either mean \(-2a^n\) (where n is an unknown exponent) or some specific value like \(-2a^2\).
- The answer options suggest you need to simplify to a format involving 8 or -8, with various exponents on A or a general number.
Could you provide the specific expression, or clarify your notation?
If you're looking to simplify something like the product or quotient of these terms, I would need the exact expression with correct exponents. That way, I can apply the exponent rules properly to help you reach the final answer.
