Chapter 6 Lesson 1:Using Properties of Exponents California State Standards Lesson Goals • Students are adept at operations involving polynomials. • Use properties of exponents to evaluate and simplify expressions involving powers. ESLRs: Becoming Competent Learners and Complex Thinkers
Properties of Exponents Product of Powers: when multiplying factors with the same base add the exponents. Examples:
Properties of Exponents Power of Product : when a product is raised to a power each factor can be raised to that power Examples:
Properties of Exponents Quotient of Powers : when dividing factors with the same base subtract the exponents. Examples:
Properties of Exponents Power of a Quotient : when a quotient is raised to a power each factor can be raised to that power Examples:
Properties of Exponents Power of Power : when raising a power to a power multiply the exponents. Examples:
Properties of Exponents Negative Exponents : when a negative exponent means “use the reciprocal” Examples:
Properties of Exponents Zero Exponent : anything raised to the zero power equals 1 Examples:

Example Simplify the expression. You have to actually divide 1.41 by 1.09
Example Simplify the expression. You have to actually multiply 1.04 and 1.39
Example The red blood cells, white blood cells, and platelets found in human blood are all generated from the same stem cells. In laboratory experiments, scientists have found that as few as 10 stem cells can grow into 1,200,000,000,000 platelets in just four weeks. The number of white blood cells generated was 0.025 times the number of platelets. How many white blood cells were generated?
