WT5BZ]In this paper, with the aid of Mathematica, exact soliton solutions and two kinds of periodic wave solutions are obtained for the 2N+1 order KdV type equations by using three types of new ansatzes, and three kinds of explictic exact solutions are also found for the 2N+1 order KP equations. These results solve the problem presented in the known reference. In addition, as the special cases of 2N+1 order KdV equations, five order KdV equation, seven order KdV equation and Schamel type MKdV equation also have the corresponding exact solutions.
