To change the base of a logarithm, you can use the formula:

\[
\log_b(a) = \frac{\log_k(a)}{\log_k(b)}
\]

where \(k\) can be any positive number.

In this case, we want to rewrite \(\log_{25}(200)\). To do this, we'll use the base 200 as follows:

\[
\log_{25}(200) = \frac{\log_{200}(200)}{\log_{200}(25)}
\]

Since \(\log_{200}(200) = 1\), the expression simplifies to:

\[
\log_{25}(200) = \frac{1}{\log_{200}(25)}
\]

However, if we rewrite it using the equivalent basis to express it directly in terms of logs, we arrive at:

\[
\log_{25}(200) = \frac{\log(200)}{\log(25)}
\]

So, among the provided options, the correct equivalent expression for \(\log_{25}(200)\) is:

**\(\frac{\log(200)}{\log(25)}\)**

Based on your provided options, that corresponds to:

**log200 / log25**

Thus, the answer is:

**log200log25 Start Fraction logarithm 200 over logarithm 25 End Fraction**
