It looks like you're using a notation that resembles mathematical expressions involving exponents. However, the notation you've provided is not entirely clear. Based on what you've given, it seems you might be looking to simplify or calculate an expression involving \(8^{-1}\) and \(7^{-2}\).
Let's clarify the expressions:
- \(8^{-1}\) means \( \frac{1}{8} \)
- \(7^{-2}\) means \( \frac{1}{7^2} \) or \( \frac{1}{49} \)
If you want to divide \(8^{-1}\) by \(7^{-2}\), you can write it as:
\[ \frac{8^{-1}}{7^{-2}} = \frac{\frac{1}{8}}{\frac{1}{49}} = \frac{1}{8} \cdot \frac{49}{1} = \frac{49}{8} \]
If you need something else, please provide a bit more detail or context!
