Look at the results of intermediate calculations, e.g., 1/Fe, then G^(1/Fe), then 1/G^(1/Fe), until you find where it goes bad. Likely you have divided by zero somewhere.

Thanks, But how can write correct expression?

There is no indication that anything is incorrect. For example, there is nothing wrong with the expression 1/x as long as you don't let x=0.
