1. ## finding power of

Hi,

one simple question (to someone who knows), i am stuck,
how to get n from equation, if i know what x and y are:

$x = y^n$

2. You need to use logarithms...

$x = y^n$

$\ln{x} = \ln{(y^n)}$

$\ln{x} = n\ln{y}$

$n = \frac{\ln{x}}{\ln{y}}$.

3. TNX , i thought it has something to do with logarithms. I really appreciate it

4. Of course, it doesn't have to be the natural logarithm. It can be the logarithm of any base... I just always use natural logarithms because they're the most often used in practice...
