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: $\displaystyle x = y^n$

You need to use logarithms... $\displaystyle x = y^n$ $\displaystyle \ln{x} = \ln{(y^n)}$ $\displaystyle \ln{x} = n\ln{y}$ $\displaystyle n = \frac{\ln{x}}{\ln{y}}$.
TNX , i thought it has something to do with logarithms. I really appreciate it
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...
