To evaluate \(\log(104 \cdot 103)\), we can use the logarithmic property that states:

\[ \log(a \cdot b) = \log a + \log b \]

So we can write:

\[ \log(104 \cdot 103) = \log(104) + \log(103) \]

Now, we can express \(104\) and \(103\) in terms of base 10 logarithms:

Let:

  • \( \log(104) = \log(10^4) + \log(1.04) = 4 + \log(1.04) \)
  • \( \log(103) = \log(10^3) + \log(1.03) = 3 + \log(1.03) \)

But rather, we can directly assume:

\[ \log(104) = 2 \log(10) + \log(4) \text{ and } \log(103) = 2\log(10) + \log(3) \]

However, given the properties of logarithms, the evaluation maintains the base in mind, hence:

\[ \log(104) = 4 + \log(3) \text{ and } \log(103) = 3 + \log(4) \]

Now, adding these gives a total of \(7\) plus any logarithmic offsets for \(4\) or \(3\).

Since \( \log(104 \cdot 103) \) will ultimately yield a direct evaluation to \(7\) under standard bases without significant imports of \(log(1.03)\) or \(log(1.04)\) retaining values within usual metric bases.

Thus, the correct final response here evaluates to:

\[ \boxed{7} \]
