IN MATH: 1. n. the number "under" the inclusion bar of the radical sign; the base with is to be raised to the fractional exponent; the argument of the root function. EX. In the radicand is 25 and the index is 2.

Type the argument then press button to simplify. Do not use fraction representation. Please approximate the fractions with a decimal. Use positive arguments for the even roots -- square root, fourth root, sixth root, ... THIS PART OF THIS PAGE can only take positive arguments for the odd roots -- cube root, fifth root -- even though they are defined for negative numbers as well. USE THE X-TO-THE-Y BUTTON BELOW! To take the square root of a number, 2 (n), raise the number to the 1/2 or .5 power.         2   To take the cube root of a number, 3 (n), raise the number to the 1/3 or .333333... power.         3 To take the fourth root of a number, 4 (n), raise the number to the 1/4 or .25 power.         4 To take the fifth root of a number, 5 (n), raise the number to the 1/5 or .2 power.         5 For other roots, use the x-to-the-y function, xy Do not use fraction representation. Please approximate the fractions with a decimal. Enter a negative without a space:  Write negative two as "-2", not "- 2."         -to-the-   Also see: RADICAL IDEAS - irrational numbers and roots VOCABULARY

IN ENGLISH: 1. as defined above.
