Product of powers law
The product of 2 powers where the bases are the same, is the base raised to the sum of the exponents
Quotient of powers law
The quotient of 2 powers where the bases are the same is the base raised to the difference of the exponents
Power of a power law
Raising a power to another power results in the base raised to the product of the exponents
Power of a product law
Where the base is itself a product raising the base to an exponent is equivalent to raising the individual factors of the product to the same exponent
Power of a quotient law
Where the base is itself a quotient raising the base to an exponent is equivalent to raising the individual parts of the quotient raised to the same exponent
Zero exponent law
Any base except zero raised to the exponent zero is always 1
