Anything to the power of 0 is 1

When you are dividing 2 exponential numbers and bases are same subtract

When multiplying 2 exponential numbers and bases are same keep base and add

when you have a power to a quoteint distribute

When you have a neg exponent flip base with the exponent keep the base and multiply the exponent Multiplication rule - Keep the base and add the exponents Division rule - Keep the base and subtract the exponents Power to a power - keep the base and multiply the exponents

Whenever you have an exponent expression that is raised to a power, you can multiply the exponent and power
