Identify the logarithmic expression given: \(\log_3(10mn)\), which is the logarithm base 3 of the product \(10 \times m \times n\).
Recall the logarithm product rule: \(\log_b(xy) = \log_b x + \log_b y\). This means the log of a product can be rewritten as the sum of the logs of each factor.
Apply the product rule to the expression: \(\log_3(10mn) = \log_3 10 + \log_3 m + \log_3 n\).
Check if any further simplification is possible. Since \(10\), \(m\), and \(n\) are separate factors, and the logs are already separated, this is the simplified sum form.
Conclude that the expression rewritten as a sum of multiple logs is \(\log_3 10 + \log_3 m + \log_3 n\).
