Chapter 8 Review Laws of Exponents
LAW #1 Product law: add the exponents together when multiplying the powers with the same base. Ex: NOTE: This operation can only be done if the base is the same! SIMPLIFY THESE ON YOUR OWN:
LAW #2 Power of a power: keep the base and multiply the exponents. Ex: NOTE: Multiply the exponents, not add them! SIMPLIFY THESE ON YOUR OWN:
LAW #3 Power of a product: Distribute the power to each number or variable in the parentheses. Ex: NOTE: Multiply the exponents, not add them! SIMPLIFY THESE ON YOUR OWN:
LAW #4 Zero exponent law: Any power raised to an exponent of zero equals one. Ex: SIMPLIFY THESE ON YOUR OWN:
LAW #5 Negative exponents: To make an exponent positive, flip the base. Ex: NOTE: This does not change the sign of the base. SIMPLIFY THESE ON YOUR OWN:
LAW #6 Quotient Property Subtract “TOP EXPONENT MINUS THE BOTTOM EXPONENT” Ex: NOTE: This operation can only be done if the base is the same! SIMPLIFY THESE ON YOUR OWN:
LAW #7 Quotient Property Distribute the power to the top and bottom of the quotient. Ex: SIMPLIFY THESE ON YOUR OWN:
