Trying to simplify a permeability expression

[NEWO]

I'm just looking through some work I did a while back and trying to simplify an expression,

epsilon_{0}epsilon_{r}=epsilon

is there an expression for

mu_{0}mu_{r}?

The relative permeability is defined as

$$\mu_{r} = \frac{\mu}{\mu_{0}} \Leftrightarrow \mu = \mu_{0}\cdot\mu_{r}$$

cool cheers
