Question

How do you calculate `log_4 43` with a calculator?

Answer 1

`ln(43)/ln(4)`

Explanation:

If your calculator doesn't have the `log_4` function, you should know that the definition of `log_n(x)` is:

`log_color(red)(n)(color(blue)(x))=ln(color(blue)(x))/ln(color(red)(n))`

note : `log_10` is often written just `log`
