Identify the logarithmic expression given: \(\log_{10}\left(5 \cdot 7\right)\).
Recall the logarithm product rule, which states that \(\log_b(xy) = \log_b x + \log_b y\). This means the log of a product can be rewritten as the sum of the logs.
Apply the product rule to the expression: \(\log_{10}\left(5 \cdot 7\right) = \log_{10} 5 + \log_{10} 7\).
Check if further simplification is possible by evaluating if \(\log_{10} 5\) or \(\log_{10} 7\) can be broken down or combined, but since 5 and 7 are prime numbers, no further simplification applies.
Conclude that the expression rewritten as a sum of logs is \(\log_{10} 5 + \log_{10} 7\).
