Reflect on radicalexpressions and their applications, and then consider how you might apply radicalexpressions to your daily life. Explain this application, and discuss what the equation might be. Did the study of these types of equations help you to understand the application better?

Why is it important to simplify radicalexpressions before adding or subtracting? How is adding radicalexpressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify.
Consider participating in the discussion by simplifying your classmates' expressions.

What law of radicals allows you to treat radicalexpressions as exponential expressions? How would you explain this to someone else and how would you explain adding like radicals? Include an example with your explanation. Use the following notation for square root: sqrt(3).

Discuss any difficulties you might have with grasping the concepts used in radicalexpressions. How would you explain square roots, cube roots, nth roots, and radicals to a student who is having difficulty understanding these concepts? What are some limitations of square root?

What is a rational exponent? How are rational exponents related to radicals? Give an example of how an expression with a rational exponent can be rewritten as a radical, using the following as an example:
(-25)^13

5 outside of the square root symbol then 3 under the square root symbol plus 15 outside of the square root symbol then 3 under the square root symbol plus 12 outside the square root symbol then 3 under the square root symbol plus 32.

I would like help understanding why it is important to simplify radicals expressions before adding and subtracting? How is adding radicals expressions similar to adding polynomials expressions? How is it different? also, an example of an radical expression would be great? I'm having hard time finding comprehensive information.
