# Are you allowed to change the sign of ln(something) when moving it to the denominator?

Like for example if I had -ln(something), could i write it as 1/ln(something), and would it be the same thing?

However , like in another question

ln (1/ n) =  -ln(n)

examples

ln (1/100) =   -4.605170186

-ln(100) = -4.605170186

@Michael,that's really something.

Try it with a number

let something = 100

-ln 100 = -4.605170185988091

1 / ln 100 = 0.217147240951626

Therefor

-ln(something) is NOT 1/ln(something),

--------------------

@Charlatan, well it's not 1/something

Cheers!

If you refer to one-in-ten versus 1/10, they are mathematically the same, but the grammar of the full sentence or phrase may require other changes.

One-in-ten people never marry. 1/10 of people never marry.

I added the word "of".

The chances of being struck by a bus are one-in-a-million. The chances of being struck by a bus are 1/1,000,000.

You do not leave the "in".

Provide a full phrase or sentence and maybe there is an exception. There are more exceptions than rules in English.
