To simplify the expression \( \frac{23^{65}}{23^{32}} \) using the quotient rule of integer exponents, we can follow the rule that states:
\[ \frac{a^m}{a^n} = a^{m-n} \]
Here, \( a = 23 \), \( m = 65 \), and \( n = 32 \). Applying the rule:
\[ \frac{23^{65}}{23^{32}} = 23^{65-32} = 23^{33} \]
Therefore, the simplified expression is:
\[ 23^{33} \]
So the correct answer is \( 23^{33} \). The other options provided (23 to the power of 97, 97, and 1 to the power of 33) are not relevant to this simplification.
