Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! You are probably talking about a cube root, fourth root, etc.
For example,  is a cube root. It means "what number can you raise to the third power and get 27?" Of course, the answer is 3, because  .
As another example,  is a fourth root. It means "what number can you raise to the fourth power and get 16?" Of course, the answer is 2, because  .
I have a complete explanation of this as a Lesson Plan in algebra.com under "Square-cubic-other-roots." Also, see my own website by clicking on my tutor name "rapaljer" anywhere in algebra.com, then go to Basic Algebra, the look for "Samples from Basic Algebra: One Step at a Time", then Chapter 5, which is a complete explanation of radicals.
