I don't understand your question. Perhaps you are having trouble writing the radical expression. Is this a cube root of a fraction? In the meantime, I do have a pretty good explanation of radicals on my own website. You might want to check it out, since it is easier for most people to understand.

To find my website, you can click on my tutor name "Rapaljer" anywhere in algebra.com. There you will find a link that takes you to my Homepage. On the Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time." Choose, "Basic Algebra", and look in "Chapter 5," where the whole chapter is devoted to square roots.

If you need a more advanced explanation, you can look in "Intermediate Algebra" in Chapter 3, or in "College Algebra" in Chapter 1 for topics on Radicals.

Here you will find my own non-traditional explanation that was written especially for students who have trouble with math. My own students all told me that it was much easier to understand than the traditional textbooks. Now, my entire curriculum from Basic Algebra to College Algebra is all posted on the website FREE!! Also, most of the hardest problems in my curriculum are already solved on the MATH IN LIVING COLOR pages that go with these sections.

In addition to the written explanations, I also have several videos that were made in my own classroom before I retired. The video on Radicals was made in Basic Algebra. To see my videos FREE, look for the page on my Homepage "Rapalje Videos in Living Color." Then choose "Basic Algebra" and look for the video on "Square Roots." It's all FREE!!
