We study Randers changes of $m$th root Finsler metrics, and provide necessary and sufficient conditions for the Finsler metric obtained by a Randers change of an $m$th root metric to be dually flat. We also prove that if the Finsler metric obtained by a Randers change of an $m$th root metric is projectively flat, then the $m$th root metric is locally Minkowskian or Riemannian.
