To evaluate \( \log(104 \cdot 103) \), we can use the product property of logarithms, which states that \( \log(a \cdot b) = \log(a) + \log(b) \).
So, we can rewrite the expression as follows:
\[
\log(104 \cdot 103) = \log(104) + \log(103)
\]
Now we can simplify \( 104 \) as \( 10^4 \) and \( 103 \) as \( 10^3 \):
\[
\log(104) = \log(10^4) = 4 \quad \text{(since \( \log(10^n) = n \))}
\]
\[
\log(103) = \log(10^3) = 3
\]
Adding these together gives:
\[
\log(104 \cdot 103) = 4 + 3 = 7
\]
Thus, the answer is:
**7**
