To simplify the expression \( \frac{a^{67}}{b^{34}} \), we can look for any common factors or apply exponent rules, but it seems like you are asking for a simplified form in relation to the other expressions listed. However, since nothing appears to cancel out and you provided separate options, we can look at how to relate it to the other given expressions.
The expression \( \frac{a^{67}}{b^{34}} \) does not simplify further by combining it with the other given options without additional context or operations between them.
If you want to express \( \frac{a^{67}}{b^{34}} \) based on the given options, none of them directly match as a simplification.
If we just refer to the simplification task:
- \( \frac{a^{67}}{b^{34}} \) can remain as it is, or we may write:
- As is: \( \frac{a^{67}}{b^{34}} \)
If instead you would like further simplifications or confirm any relationships with the additional options (like \( a^{33}, ab^{33}, 23 \)), please clarify your request!
