Question

What is an equivalent expression in terms of natural logarithm?

Answer 1

\[\log_{5}67\]

Answer 2

Use the change of base law:

\[\log_b a = \frac{\log_k a}{\log_k b}\]If you are using the natural logarithm, \(k = e\) and you have \[log_b a = \frac{\log_e a}{\log_e b} = \frac{\ln a}{\ln b}\]
