Determine the relationship between graphic patterns and what they represent mathematically. This video focuses on how fractals can be a visual representation of negative exponents, which are a way to express repeated division.

In this program, we learn that the power of a quotient is equal to the quotient obtained when the dividend and divisor are each raised to the indicated power separately before the division is performed.
Apply your critical thinking skills to learn about multiplication and division of exponents. This interactive exercise focuses on positive and negative exponents and combining exponents in an effort to get you to recognize patterns and determine a rule.

Students will apply their critical thinking skills to learn about multiplication and division of exponents. This interactive exercise focuses on positive and negative exponents and combining exponents in an effort to help students recognize patterns and determine a rule.
In Module 1, Topic A, students begin by learning the precise definition of exponential notation where the exponent is restricted to being a positive integer. In Lessons 2 and 3, students discern the structure of exponents by relating multiplication and division of expressions with the same base to combining like terms using the distributive property, and by relating multiplying three factors using the associative property to raising a power to a power.
Lesson 4 expands the definition of exponential notation to include what it means to raise a nonzero number to a zero power; students verify that the properties of exponents developed in Lessons 2 and 3 remain true. Properties of exponents are extended again in Lesson 5 when a positive integer, raised to a negative exponent, is defined. In Lesson 5, students accept the properties of exponents as true for all integer exponents and are shown the value of learning them, i.e., if the three properties of exponents are known, then facts about dividing numbers in exponential notation with the same base and raising fractions to a power are also known.
In this activity from Khan Academy, students will review the common properties of exponents that allow them to rewrite powers in different ways. For example, x²⋅x³ can be written as x⁵. This activity has embedded videos, practice problems with immediate checks for the correctness of answers, and an explanation option. This review can be assigned to Google Classroom.

In this MathPlanet lesson, students will learn the properties of exponents. The students will learn to multiply powers, apply the power of a power property, divide exponents, raise a quotient to a power, and what to do with a negative exponent. This lesson includes a video lesson and can be added to Google Classroom.
