An analytical solution of the QCD evolution equations for the singlet and gluon distribution is presented. We decouple DGLAP evolution equations into the initial conditions by using a Laplace transform method at NnLO analysis. The relationship between the nonlinear behavior and color dipole model is considered based on an effective exponent behavior at low x values. We obtain the effective exponent at NLO analysis from the decoupled behavior of the distribution functions. The proton structure function compared with HERA data from the inclusive structure function for and GeV2.
