To evaluate \( \log(10^4 \cdot 8) \), we can use the properties of logarithms. Specifically, we can use the product property of logarithms, which states that:
\[ \log(a \cdot b) = \log a + \log b \]
Using this property, we can break down the expression:
\[ \log(10^4 \cdot 8) = \log(10^4) + \log(8) \]
Next, we can evaluate \( \log(10^4) \):
\[ \log(10^4) = 4 \]
Thus, we can substitute this back into our expression:
\[ \log(10^4 \cdot 8) = 4 + \log(8) \]
Therefore, the correct evaluation is:
\[ \log(10^4 \cdot 8) = 4 + \log(8) \]
The correct answer from the options is:
log(104⋅8)=4+log8
