The anisotropic Bianchi type I in multi-scalar field cosmology is studied with a particular potential of the form V= V 0 e−[λ 1 ϕ 1+⋯+ λ n ϕ n], which emerges as a condition between the time derivatives of their corresponding momenta. Using the Hamiltonian formalism for the inflation epoch with a quintessence framework we find the exact solutions for the Einstein-Klein-Gordon (EKG) system with different scenarios specified by the parameter λ 2=∑ i= 1 n λ i 2. For the quantum scheme of this model, the corresponding Wheeler-DeWitt (WDW) equation is solved by applying an appropriate change of variables and suitable ansatz.
