Beyond the Answer
For \( 5^{4} \cdot 5^{-2} \), remember that when multiplying exponents with the same base, you add the exponents. So, \( 5^{4 + (-2)} = 5^{2} \). That simplifies to \( 25 \)! Now, looking at \( \frac{10^{7}}{10^{4}} \), you subtract the exponents since it's division. Thus, \( 10^{7 - 4} = 10^{3} \), which equals \( 1000 \). Lastly, for \( \frac{3}{3^{-2}} \), you can rewrite it as \( 3 \cdot 3^{2} = 3^{1 + 2} = 3^{3} \), giving you \( 27 \).
