Unit 7 – Exponents Topic: Introduction to Exponents
Exponential Vocabulary • Exponent • Power/# of times something is multiplied by itself • Ex. 63; 3 is an exponent • Base • Value with an exponent/superscript • Ex. x5; x is a base • Coefficient • Number in front of a variable • Acts as a multiplier • Ex. 2y3; 2 is a coefficient; the exponent does not affect the coefficient, only the base
Exponential Laws (Put these on a note card) • Zero Law of Exponents • Any base other than 0 raised to the 0 power equals 1. • Negative Law of Exponents • Any base other than 0 raised to a negative power is the same as raising the reciprocal of the base to the positive value of the power. • JOURNAL ENTRY • TITLE: Exponential Laws • Explain, either in words or mathematically, why you think these laws are true.
