The data collection instrument used was a diagnostic questionnaire applied to the research target group, initially composed of three closed questions, whose objective was to know the profile of the students involved and two questions related to the potentiation content. Regarding the results, it was observed that the students have difficulties mainly in the definition of potentiation attributing in most cases the multiplication between base and exponent, as well as in the powers that involve negative numbers.
