```Hello MathGroup,
My last confession was...
er...
NSolve seems able to carry through significance arithmetic. FindRoot
and NDSolve seem inable to do so.
I would like to be able to solve the following equation for acCap
assuming cNapRatio->0
(sorry about the FullForm, but I had to rid the post of the one way
Notations I made), does anyone know a way to get Mathematica to do
this?

Equal[Times[Power[Log,-1],Log[acCap[cNapRatio]]],
Plus[Times[0.6107999999999999999`0.9956786262173576,cNapRatio],
Times[-2.0360000000000000001`2.9999999999999996,
Plus[Times[-0.0061540230743798795`0.9978339382434933,
Power[acCap[cNapRatio],-2],
Power[Power[acCap[cNapRatio],2],Rational[1,2]]],
Times[Power[2,Rational[-1,2]],
Power[Plus[Times[2,cNapRatio],
Times[0.0410268204958658633`3.3010299956639817,
Power[acCap[cNapRatio],-2],
Power[Power[acCap[cNapRatio],2],Rational[1,2]]]],
Rational[1,2]],
Power[Plus[1,
Times[Power[2,Rational[-1,2]],
Power[Plus[Times[2,cNapRatio],
Times[0.0410268204958658633`3.3010299956639817,
Power[acCap[cNapRatio],-2],
Power[Power[acCap[cNapRatio],2],Rational[1,2]]]],
Rational[1,2]]]],-1]]]]]]
