When dividing radicals and the top variable's degree is lower than the bottom's, is it negative? And if so, how does it become written in context of the radical's root(ex: third root of X to the negative third power)?

$$\\x^4\div x^6=x^{4-6}=x^{-2}\\\\
$Now I will look at it differently$\\\\
x^4\div x^6=\frac{x^4}{x^6}=\frac{\not{x}\not{x}\not{x}\not{x}^1}{\not{x}\not{x}\not{x}\not{x}xx}=\frac{1}{x^2}\\\\
$so put these together and you get$\\\\
x^{-2}=\frac{1}{x^2}$$

 

If you want to get rid of a negative indice you put the thing that is raised to the neg power on the other side of the fraction line and change the negative to a positive.  :)
