replace exp by Exp..and everything will work fine Please remember..in Mathematica..all functions starts with capital letters In[36]:= A = 1*10^(-4); k = 2/3; g = 1.12*10^(-11); Attenuation = 0.23026*0.475*10^(-3); L = 7200; Leff = (1 - Exp[-Attenuation*L])/Attenuation; FindRoot[x - A*Exp[k*g*x*Leff - Attenuation*L], {x, 0}] Out[42]= {x -> 0.0000454986} ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
