When solving a radical equation...

What is the principle of powers? Describe in your own words. When solving a radical equation, how do we use the principle of powers to eliminate radicals? Demonstrate with an example—feel free to choose a problem from the textbook. Make sure that it is different from the examples already posted in the class discussion by your classmates. Then provide an example for your classmates to solve. Hint: work through your example before you provide it for your classmates to be certain it does have a solution.
