Geometric Mean Radius of Hollow Conductor

[sandy.bridge]

Homework Statement

$GMR_{hollow cylinder}=Re^{-Kμ}$ where $K=\frac{AR^4-R^2r^2+Br^4+r^4ln(R/r)}{(R^2-r^2)^2}$, where R is the outer radius and r is the inner radius, and mu is the relative permeability. We are to determine the numerical values of A and B.

I am stumped on how to begin attempting this question. Any hints or help would be greatly appreciated.
