To calculate the value of \( \log_3(15) \), we can use the change of base formula, which is:

\[
\log_b(a) = \frac{\log_c(a)}{\log_c(b)}
\]

For simplicity, we typically use base 10 (common logarithms) or base \(e\) (natural logarithms). Using base 10, the expression becomes:

\[
\log_3(15) = \frac{\log(15)}{\log(3)}
\]

Now, let's calculate:

\[
\log(15) \approx 1.1761
\]
\[
\log(3) \approx 0.4771
\]

Therefore:

\[
\log_3(15) \approx \frac{1.1761}{0.4771} \approx 2.465
\]

So, \( \log_3(15) \approx 2.465 \).
