How to divide radicals with rational exponents

Im stuck on the _process_ of simplifying a radical with an exponent inside.

Example: Sq.root [ x^6 ] divided by Sq.root [ y^18 ].

*Brackets denote the entity under the radical sign.


Im not looking for an answer to the problem, but a guide on how to correctly simplify the problem. Thanks

Prolly the easiest way out of this is to consider the radical sign as raising the radicand to the 1/2 power.

Sq.root [ x^6 ] divided by Sq.root [ y^18 ] becomes [ x^6 ]^(1/2)
divided by [ y^18 ]^(1/2) with some cautions... if the x and y are
negative then you'd need absolute value signs about the roots:
Instead of just x^3/y^9 you'd need |x^3/y^9|.

x^6=(x^3)^2
y^18=(y^9)x(y^9)=(y^9)^2
