Consequent upon these definitions and properties neutrosophic cubic weighted exponential averaging and dual neutrosophic cubic weighted exponential averaging aggregation operators are defined. A multi attribute decision making method is then developed for proposed aggregation operators. An example is constructed as an application. The validity of multi attribute decision making method is also tested and comparative analysis is provided to compare these aggregation operators with existing results. 2020 47 71 339 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.040105 https://www.americaspg.com/journal/21/article/339 https://www.americaspg.com/storage/8449.pdf
