So the product of the first 3 terms is now well established and is of order 5.   \begin{equation}  N =\underbrace{\overbrace{R}^{\approx10} \times \overbrace{f_p}^{\approx 1} \times \overbrace{n_e}^{\approx 0.2}}_{\sim 5} \times \underbrace{f_l \times f_i \times f_c \times L}_{?}$ L}_{?}  \end{equation}\label{Drake}  We can then simplify the Drake equation and re-write it in its "2014 form" as:
