Problem: is not a list of numbers with dimensions

When run the below code,


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}]

 

It executes the below solution,

 

FindRoot::nlnum: The function value {0.-0.0001 exp[-0.787489+0. \

(1.+Times[<<2>>])]} is not a list of numbers with dimensions {1} at \

{x} = {0.}.

 

I need your help about numerical and Alpha_numeric solution of this problem.


 

f(x)= x-A*exp[k*g*x*Leff-Attenuation*L
