This is an 8 question ExamView bank of dynamic bimodal questions. Numbers larger than 10 and smaller than 1 are included, and for each there is a question with a positive exponent and a question with a negative exponent.
Bimodal: questions can be toggled between multiple choice and short answer
Dynamic: questions and answers can be given new numbers at the press of a button
I use these as worksheets for practice/remediation. Typically I print out a different version for each student with answers on the back or in a packet I keep at my desk.
