To find \( \ln 55 \) using the Product Rule of Logarithms, you can express 55 as the product of 11 and 5:
\[ \ln 55 = \ln(11 \times 5) \]
According to the Product Rule of Logarithms:
\[ \ln(a \times b) = \ln a + \ln b \]
Applying this to our expression gives:
\[ \ln 55 = \ln 11 + \ln 5 \]
Now, we can substitute the given values:
\[ \ln 11 \approx 2.398 \] \[ \ln 5 \approx 1.609 \]
Adding these together:
\[ \ln 55 \approx 2.398 + 1.609 \approx 4.007 \]
Therefore, the correct answer is:
4.007
