Question 139376: Describe two laws of exponents and provide an example illustrating each law. Explain how to simplify your expression. How do the laws work with rational (fractional) exponents? Provide the class with a third expression to simplify that includes rational (fractional) exponents.
The two laws I came up with are;
(ab)^m= a^mb^m = To raise a product to a power, we can raise each factor to the power.
a^m • a^n = a^m+n = In multiplying, we can add exponents if the bases are the same.
I do not know how to do the rest.
