one (and perhaps the only) example is:2^4=4^2
what more examples are there?

ah, this is from c++ language which means does not equal to (m doesn't equal to n).Originally posted by StephenPrivitera
I think he means to say that 4!=24[x=] 2
Your example 2^4=4^2 doesn't satisfy the condition m!=n (m=4, n=2, 4![x=]2)
Prove it.Well...it is quite simple to prove that m must be equal to k*n...where k is an integer...

n^(k*n)=(n*k)^n
(n^k)^n=(n*k)^n
n^k=n*k...
n^(k-1)=k...
if n=1...k=1...wrong...m=n...
if n=2...2^(k-1)=k...if k>2 then it's wrong...so k=2...m=4...
if n>2...n^(k-1)>2^(k-1)>k...(for k>1...)
So...n=2...m=4...it's the only solution...
Well, even if they were integers, it is not always possible to express one integer as k*n.Ooops...sorry...I thought m and n were integers...sorry again...stupid me

The equation N^m=m^n when m=n represents a special case of exponential equations where the base and the exponent are equal. This means that any number raised to a power that is equal to itself will result in the same number.
The equation N^m=m^n when m=n is applicable in various fields of science, including physics, chemistry, and engineering. It is used to model exponential growth and decay, such as population growth, radioactive decay, and compound interest.
The equation N^m=m^n when m=n is true because it follows the properties of exponents. When the base and the exponent are equal, the result will always be the same number. Additionally, this equation can be proven mathematically using logarithms.
Yes, there are certain cases where the equation N^m=m^n when m=n does not hold true. For example, when the base and the exponent are both 0, the equation becomes 0^0=0^0, which is considered indeterminate. Additionally, imaginary numbers and negative numbers can also cause exceptions to this equation.
The equation N^m=m^n when m=n demonstrates a symmetrical relationship between the base and the exponent. This means that when the base and the exponent are swapped, the result will still be the same. This symmetry is also evident in the graph of the equation, where the curve is symmetrical about the line y=x.
