Moreover, we provide De Moivre's formula for the light-like Pauli quaternions. Additionally, we give the nth roots of the matrix representation of Pauli quaternions. Moreover, we exemplify some of the results with illustrative examples to support the main formulas.eninfo:eu-repo/semantics/closedAccessPauli quaternionmatrix representationEuler's formulaDe Moivre's formulaArticle10.1142/S02198878225017542-s2.0-8513907758111Q219WOS:000848629500003Q2
