SUMMARY

The discussion focuses on solving the implicit equation k = (c^m - a^m) / (b^m - a^m) numerically, where a, b, c, and k are constants. Participants suggest transforming the variables by using exponential functions, specifically x = exp(m), a = exp(u), b = exp(v), and c = exp(w). This transformation simplifies the problem to finding positive roots of a polynomial, making it more manageable for numerical methods. The conversation emphasizes the importance of defining the variable m in relation to the constants for effective numerical solutions.

Equation is:
k=(c^m-a^m)/(b^m-a^m)
where a, b, c, and k are constants. How to solve it (numerical?) Detail please.

Thanks

Solve it with respect to what? m?
It could help you to assume:

x=exp(m)
a=exp(u)
b=exp(v)
c=exp(w)

you would solve for x, and with some luck it could be easy.
It would be almost like finding (positive) roots of a polynomial.
