To simplify the expression \(\frac{a^{67}}{b^{34}}\), we cannot combine or reduce the terms further with the given terms since they have no common base. Therefore, the simplified expression stays as it is:
\(\frac{a^{67}}{b^{34}}\)
Based on the provided responses, it appears that none of the options match the direct simplification correctly. However, if you are looking for an answer that reflects the original expression, the closest match from your options appears to be "a67b34" by not factoring anything, but it's not a simplification.
So the most accurate response among the choices for the simplification task is:
\[\frac{a^{67}}{b^{34}}\]
If you need an expression in a different form, please clarify!
