$\square$
B. The equation is true.
Solution
Solution Steps
To determine whether the given equation is true or false, we can use properties of logarithms. Specifically, we can use the property that \(\log(a) - \log(b) = \log\left(\frac{a}{b}\right)\). We will apply this property to the left side of the equation and compare it to the right side. If both sides are equal for all valid \(x\), the equation is true; otherwise, it is false.
Step 1: Analyze the Left Side
We start with the left side of the equation:
\[
\log(x + 5) - \log(6x)
\]
Using the property of logarithms, we can combine the logs:
\[
\log\left(\frac{x + 5}{6x}\right)
\]
Step 2: Analyze the Right Side
The right side of the equation is:
\[
\frac{\log(x + 5)}{\log(6x)}
\]
This expression does not simplify directly to a logarithmic form that can be easily compared to the left side.
Step 3: Compare Both Sides
We have:
\[
\log\left(\frac{x + 5}{6x}\right) \quad \text{(left side)}
\]
and
\[
\frac{\log(x + 5)}{\log(6x)} \quad \text{(right side)}
\]
Since the left side simplifies to a single logarithmic expression while the right side remains a fraction of logarithms, we conclude that these two expressions are not equal for all valid \(x\).
Final Answer
The equation is false. The correct equation is:
\[
\log(x + 5) - \log(6x) = \log\left(\frac{x + 5}{6x}\right)
\]
Thus, the answer is A.
\(\boxed{\text{A}}\)
