To simplify the expression \(\frac{a^{67}}{b^{34}}\), you can rewrite it as:
\[ a^{67} \cdot b^{-34} \]
However, since none of the answer choices fit that format, based on standard simplification, \(\frac{a^{67}}{b^{34}}\) cannot be simplified further unless specific values for \(a\) or \(b\) are given.
The simplified expressions provided are not mathematically equivalent to \(\frac{a^{67}}{b^{34}}\). If you're looking for a more appropriate answer based on the provided options:
- The original expression: \(\frac{a^{67}}{b^{34}}\) remains unchanged.
So, the answer that matches in form would be:
\[ \frac{a^{67}}{b^{34}} \]
This is the correct response.
