This Problem Set is a part of the Lesson 5, Unit 4, Grade 6. In this lesson, students use new terminology (base, squared, and cubed) and practice moving between exponential notation, expanded notation, and standard notation. Students understand that a base number can be represented with a positive whole number, positive fraction, or positive decimal and that for any number a, a^m is defined as the product of m factors of a. The number a is the base, and m is called the exponent or power of a.
