Question

The formula log in a natural logarithm can be written as?

Answer 1

Given the logarithmic expression:

`\log_545`

According to the change of base formula,

`\log_BA=\frac{\ln A}{\ln\text{ B}}`

Thus, expressing the logarithm expression in a natural logarithm,

`\log_545=(\ln45)/(\ln5)`

Hence, we have

`(\ln45)/(\ln5)`
