To condense the expression, you can use the property of logarithms that states \( \log a + \log b = \log(ab) \). So, you would have: \( \log 125 + \log 8 = \log(125 \cdot 8) \). Now, calculate \( 125 \cdot 8 = 1000 \). Therefore, the expression simplifies to: \( \log 1000 \). Since 1000 is equal to \( 10^3 \), you can further simplify it to: \( \log 1000 = 3 \). So the final condensed expression is: \( \log 125 + \log 8 = \log 1000 = 3 \).
