This paper considers nonlinear fractional differential equations with unknown analytical solutions. The Adomian decomposition and the fractional power series methods are adopted to approximate the solutions. The two approaches are illustrated and compared by means of four numerical examples.engAdomian decomposition methodFractional power series methodNonlinear fractional differential equationsjournal article10.3390/math9091070
