```
replace exp by Exp..and everything will work fine
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}
