Mathematics is not only used to advance the human mind, but mathematics also has many learning objectives, such as: 1). To make it easier for us to understand mathematical design, 2). Using logic in solving patterns and characteristics, 3). Aims to solve various problems that include problem solving abilities, 4). Aims to communicate with symbols, tables, etc., 5). Aims to respect the benefits of mathematics in our lives. This research was conducted at SMK N 2 Bukittinggi with the aim of knowing the level of problem-solving ability of students in working on questions of exponential numbers and forms of roots. The research instruments used were observation and tests of mathematical questions on the material of starting numbers and roots. The sampling technique used for this research is simple random sampling. The subjects of this study were 35 students in Class X Culinary 1 at SMK N 2 Bukittinggi for the 2022/2023 academic year.
