Solving for variable N when it is used as a base and exponent

Click For Summary
SUMMARY

The discussion focuses on solving the equation (n/2)^n = c for the variable n, where c is an integer constant. The user attempts to manipulate the equation using logarithmic properties, specifically with base 2 logs, leading to the expression n(log(n) - 1) = log(c). Despite these efforts, the user encounters difficulties in further simplifying the equation, indicating that advanced mathematical techniques may be necessary to isolate n. The conversation highlights the challenges of combining n as both a base and an exponent within logarithmic functions.

Homework Statement



I would like to solve the following equation for the variable "n"
The variable c represents any integer constant.

(n/2)^n = c

The goal is to get this in some form of n = ?

Homework Equations



The logarithm properties.

The Attempt at a Solution



I've tried using logs but I get stuck because there seems to be no way to somehow combine n as a base, and n as an exponent. Is this something that requires higher level math?

---------------------------------------
Let all logs be of base 2

(n/2)^2 = c
log(n/2)^n = log(c)
n*log(n/2) = log(c)
n(log(n)-log(2)) = log(c)
n(log(n)-1) = log(c)

Here I get stuck because any further logarithm manipulation only goes in circles.

Can anyone teach or point to me what kind of math I need to know to solve this please?

Why didn't you move -log(2) over to the other side? Also, I like natural logs better when you're dealing with variables because you don't have to worry about the base.
