By the way, I am a 72 year old lady trying to learn Algebra. So far, so good. Thanks. Mary 1 solutions Answer 56269 by stanbon(57387)   on 2007-04-16 20:25:02 (Show Source): You can put this solution on YOUR website! You know that every Real number has two square roots: 2 is the pricipal square root of 4 and -2 is the secondary square root of four. -------------- when it comes to cube roots and higher it gets a little more complecated. The priciple cube root of 8 is 2 because 2*2*2=8 There are two other cube roots but you have to understand the complex number system to express them. Similarly there are 4 4th roots of numbers, 5 5th roots of numbers, and, in general, n nth roots of numbers. When you study trigonometry and find out about a Frenchman named DeMoivre you will find out how to calculate these "other" roots. Hope this helps. Cheers, Stan H.
