In this mathematical investigation, students explore patterns when radicals are raised to different powers (first even powers to help recognize patterns and then odd powers to check that the patterns they found actually works). Then, as they continue working with different radical expressions (raised to even and then odd powers), they discover the rules for writing radical expressions in exponential forms. In mark band 7-8, students expand their investigation into cube roots, 4th roots, and nth roots as well.
