1.Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression to simplify.
2.Describe two laws of exponents and provide an example illustrating each law. Explain how to simplify the expression. How do the laws work with rational exponents? Provide a third expression to simplify that includes rational (fractional) exponents. Please see attachment.
This provides explanations of working with radical expressions and laws of exponents.
