摘要：

This paper is presented to investigate the exact solutions to the modified ZakharovKuznetsov equation that have a critical role to play in mathematical physics. The tan (phi (zeta) /2)expansion, (m + G '(zeta)/G(zeta))-expansion and He exponential function methods are used to reveal various analytical solutions of the model. The equation regulates the treatment of weakly nonlinear ion-acoustic waves in a plasma consisting of cold ions and hot isothermal electrons throughout the existence of a uniform magnetic field. Solutions in forms of W-shaped, singular, periodic-bright and bright are constructed.
