Series
If series $$f(x)=a_1x+a_2x^2+a_3x^3+...$$

$$a_n=\ln(n)$$

If $$a_n/\ln(c)=\ln(n)/\ln(c)$$

What is a constant c that makes the value $$ln(n)/ln(c)=nr$$? where nr is a constant that makes return to whole number n and constant r — Preceding unsigned comment added by 37.98.231.36 (talk) 13:02, 8 April 2018 (UTC)


 * No, logarithmic functions are not linear functions. Maybe, instead of posting repeated cryptic equations, you should try to explain what you're actually trying to do.  (Also, LaTeX knows \ln .) --JBL (talk) 14:49, 8 April 2018 (UTC)
 * The IP geolocates to Iraq so their English is probably not very good and they don't know how exactly to formulate their question. As precisely stated, there exists no constant c such that for every natural number n and for some constant r, $$\ln(n)/\ln(c) = nr $$. The original poster is strongly encouraged to adopt the hyperlinked terms in order to better formulate their question.--Jasper Deng (talk) 17:40, 8 April 2018 (UTC)
