To simplify \( \frac{746^{25}}{746^{4}} \), we can use the quotient rule of exponents. The rule states that when you divide two powers with the same base, you subtract the exponents:
\[ \frac{a^m}{a^n} = a^{m-n} \]
In this case:
- The base \( a \) is \( 746 \).
- The exponent \( m \) is \( 25 \).
- The exponent \( n \) is \( 4 \).
Applying the quotient rule:
\[ \frac{746^{25}}{746^{4}} = 746^{25-4} = 746^{21} \]
So, the final answer is:
\[ 746^{21} \]
Thus, the correct answer among your options is:
Subtract the exponents to get 21.
And the final result is:
746^{21}.
