KEY CONCEPTS: - Whenever you have an exponent followed by another exponent, keep the base and multiply the two exponents

KEY CONCEPT: ANY power with an exponent of zero, regardless if the BASE of the power is a number or a variable is equal to 1 a^0=1 999^0=1

KEY CONCEPTS: - when dividing Powers with the same base, subtract the exponents. - bases must be the same in order for you to be able to simplify such expressions
