I was working on a Euphoria program to solve non lin's but haven't gotten
back to it in a while.  i hope to take a break from windows programming
soon and get back to it.

Offhand, this looks unsolvable in general because of all the multiplys.
Are you sure there are not any additions such as:
  135 = a*1000^b + e^(c*(0.2)) + (0.1)^d   ???
These can often be solved to some degree using non linear equation
solving methods.  Can't solve them using linear algebra in general.
Also, still need n equations to solve for n variables in general.
