27 4log 72 .

To solve the expression \( 27 \cdot 4 \log 72 \), we can break it down step by step.

1. First, we need to compute \( \log 72 \). If no specific base for the logarithm is given, it's commonly assumed to be base 10 or the natural logarithm (base \( e \)). Assuming base 10:

   \[ \log_{10} 72 \approx 1.856 \]

2. Next, we multiply this by 4:

   \[ 4 \log 72 \approx 4 \cdot 1.856 \approx 7.424 \]

3. Finally, we multiply this result by 27:

   \[ 27 \cdot 7.424 \approx 200.448 \]

Therefore, \( 27 \cdot 4 \log 72 \approx 200.448 \).
