To simplify \( a^{67}b^{34} \), we can separate the parts.
The expression \( a^{67}b^{34} \) is already simplified in terms of its form; there are no common bases to combine or exponents to reduce.
So the correct answer is:
\( a^{67} b^{34} \)
If you want it presented differently, it can also be represented as:
Start Fraction \( a^{67} \) over \( b^{34} \) End Fraction
If that's one of the choices, you can use that, but otherwise, \( a^{67}b^{34} \) is the simplest form. None of the other options provided (like \( a^{33} \) or \( ab^{33} \)) correctly represent the original expression.
