We present a set of formula to extract exponents of the longitudinal structure function and reduced cross section from the Regge-like behavior at small x. The exponents are found to be independent of at NNLO analysis. As a result, we show that the reduced cross-sectional exponents do not have the same behavior at some values of x. This difference predicts the non-linear effects and some evidence for shadowing and antishadowing at LHeC. Also the ratio is calculated and compared with the corresponding HERA data. Our calculations show a very good agreement with the DIS experimental data throughout the small values of x.
