Question

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
