In this study, the exact black hole (BH) solutions of Brans-Dicke (BD) theory were obtained under the influence of power-Maxwell nonlinear electrodynamics. Since the Jordan frame field equations are strongly coupled, they cannot be solved directly. Using the conformal transformations, we translated them to the Einstein frame, where the field equations are decupled, and the theory is the well-known Einstein-dilaton (Ed) gravity. Through solving the equations, three novel classes of Ed-power-Maxwell BHs were introduced. After calculating the thermodynamic quantities, using the appropriate approaches, we showed that the first law of BH thermodynamics is valid in the Einstein frame. Also, thermal stability of the BHs was analyzed using the canonical ensemble method. The exact BH solutions of BD-power-Maxwell theory were obtained from their Einstein correspondence by applying the inverse conformal transformations. We showed that thermodynamic quantities remain invariant under conformal transformations. As the result, thermodynamical first law is valid for the Jordan frame BHs and, their thermal stability properties are just like those of Einstein frame.
