Given a number 
, the positive root (if there is a positive solution) of ![$\sqrt[x]{n}$](http://latex.artofproblemsolving.com/7/a/b/7ab6da932f9174c01399d495bfc2966b258bbf83.png)
is the solution greater than zero. The positive root of a polynomial 
is a value greater than zero so that, when put in place of 
, makes the expression zero
