'''Note:''' |
'''Note:''' If you are looking for a decimal expansion of an integer root, one must select the proper number of digits for N, that is, ''2000'', ''2001'', ''2002'', etc..., otherwise the result will be the digits of the nth root of 20, 2000, etc...<br/> |

For example, If you use "3 <.@%: (2*10x^2*200'''0''')" instead of "3 <.@%: (2*10x^2*200'''1''')", you will get an output starting with "271441761659490657151808946...", which are the first digits of the cube root of 20, not 2. |

This constraint is independent of the task requirements, except in an illustrative sense, so will not be developed further, here. |
