product of powers property
This property tells us how to simplify products that have two powers, and the same base. This property says that for all m and n, and all nonzero b, bm bn= bm+n. This allows us to group factors with the same base.
quotient of powers property
to divide two powers with the same nonzero base, subtract the exponent of the denominator from the exponent of the numerator
power of a power property
Multiply the power outside the parenthesis by the power of each base inside the parenthesis
power of a product property
find the power of each product and multiply
power of a quotient property
to find a power of a quotient, find the power of the numerator and the power of the denominator and divid
