I was adding some questions to a quiz from a textbook's question bank, and on one version of a quiz was -4^3 but another version had -5^4. It would be really hard to distinguish the level of understanding each student has for evaluating powers with even or odd exponents, whether a base is negative or positive or if there is a leading negative outside the base. Thus, I created my own question bank.
These problems are designed to assess mastery of handling negatives properly when evaluating a power. Exponents are small (2,3, or 4) and the base is also small. I did not want students to get hung up on computation, rather these questions target understanding of how to properly identify a base and when a power evaluates to a negative value.
All of the problems are dynamic, but with the few choices for small numbers, the variation will be somewhat limited (except the couple of questions with fractions). This question bank does, however, provide all of the possible permutations in a single place to avoid wide variation between multiple versions of the same assessment.
