Abstract
In this article, we use the fractional complex transform with help of the optimal homotopy analysis method (OHAM) to obtain approximate analytical solution for the time fractional Zakharov-Kuznetsov equation. Fractional complex transform is convert the nonlinear fractional Zakharov-Kuznetsov equation to the corresponding nonlinear ordinary differential equation which have been solved using the OHAM. This optimal approach has general meaning and can be used to get the fast convergent series of solutions of the different type of nonlinear fractional differential equations.
