This Instructional Activity is a part of the Lesson 3, Unit 1, Grade 8. As an alternative to the discussion, provide students with the four questions shown and encourage them to work with partners or in small groups to find a relationship in each case if one exists. You might consider assigning one case to each group and present their findings to the class. Students will find the latter two cases to be much more complicated. From the point of view of algebra and arithmetic, the most basic question about raising a number to a power has to be the following: How is this operation related to the four arithmetic operations?
