To simplify the expression \( a^{67} b^{34} \), we first look at the components.
Given the options, it looks like you are asking how to express that in a different way.
The expression \( a^{67} b^{34} \) itself cannot be simplified further without specific values for \( a \) and \( b \).
However, if we were to express \( a^{67} b^{34} \) in the form of a fraction as suggested in one of the responses, it would just look like:
\[ \frac{a^{67}}{b^{34}} \]
Or, if you wanted to express it in a way that isolates the exponents, we could say it highlights both parts:
- \( a^{67} \)
- \( b^{34} \)
If the question is about expressing this differently without numerical simplification, I would say:
- As a combined term: \( a^{67} b^{34} \)
Thus, none of the suggested options are a valid simplification without additional context or specifications for what you aim to achieve. If additional constraints or goals were provided, please clarify for further assistance.
