Question:
<p>Find the inverse of \(y=5^{\log x}\).</p>
Step-by-Step Solution
<div class="solution"><p>log y=(log 5)(log x) \to log x=log y/log 5 \to x=10^{log y/log 5}=y^{1/log 5}.</p><div class="key-concept"><strong>Key Concept:</strong> Inverse via logarithm -- base-10 log of both sides
Correct Answer: x = y^{1/log 5}
