Talk:Algebra/Roots and Radicals

just rember that the square root of any radical is positive and negative

ex.  radical 16 = +4,-4


 * No, the square root of a positive number is the positive number whose square etc. This implies that sqrt(x*x) = abs(x) and not that sqrt(x * x) = +/- x. Albmont 16:48, 9 November 2006 (UTC)

Please define the word "Radical" in the body of this page. What is the difference between exponent and radical? Thanks. Jim Kelly - http://www.k-12math.info/e6home.html Please note that roots don't need to be integers.
