 {{{((-27x^18)/(y^-36))^(2/3)}}}


 {{{((-3^3*(x^6)^3)/(1/y^36))^(2/3)}}}


{{{(((-1)3^3*(x^6)^3)/(1/(y^12)^3))^(2/3)}}}


{{{((-1)*(3x^6)^3*(y^12)^3)^(2/3)}}}


{{{root(3,((-1)*(3x^6)^3*(y^12)^3)^2)}}}


{{{root(3,(((-1^2)*(3x^6)^2)^3*(y^12)^2)^3)))}}}


{{{root(3,-1^2*(3x^12)*(y^24))}}}


{{{root(3,-1^2)*9x^12*y^24}}}
