Question

How do you calculate `Log_4 14`?

Answer 1

I supposed that you can use a calculator.

Explanation:

One way involves the use of a scientific calculator that allows you to evaluat a natural logarithm indicated as `ln`.
You can change base of your original log using a well known relationship where you get a fraction of two logs in the new base and as arguments the old argument and the old base:
`log_4(14)=ln(14)/ln(4)=1.90367`

You can test this result considering that (using the definition of log):

`4^(1.90367)=13.9998~~14`
