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
