What are the two steps for simplifying radicals? Can either step be deleted? If you could add a step that might make it easier or easier to understand, what step would you add?

Did you know that we will do your My Math Lab or Carnegie Learning work for you? We have earned extremely great grades and reviews doing this work for people.. Check it out by visiting our website...

The first step to simplifying a radical is breaking it down into its perfect square numbers, (by perfect square numbers I mean numbers like 4, 9, 16, 25 etc.) for instance in the 12. This can be broken down into 3x4. Four is a perfect square number. Therefore its square root can be pulled out of the radical. In this case 2. There is however still left a three under the radical so the simplified radical looks like. 23. There isnt really a step that can be eliminated in this process. I f I were to add a step or break it down for someone else to understand I would simply explain that the simplest way to break down a radical is to break it down to its LCD, and any numbers left over that have pairs of 2 can be pulled out of the radical. A radical term for the class to simplify is 147.
