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 exponents? Provide the class with a third expression to simplify that includes rational (fractional) exponents

Answer 1

x^a * x^b = x^(a+b)

(x^a)^b = x^ab

x^(a/b) = the bth root of x^a, so

[x^(a/b)]^b = x^a

The laws work with all rational exponents

Answer 2

thank you

Answer 3

7x-5=72
