Question 1091537
{{{ ((-64x^3)/y^-6)^(2/3 )}}}


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


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


{{{ root(3,(64(-x)^3*y^6)^2 )}}}


 {{{root(3,4^6(-x)^6*y^12 )}}}


 {{{root(3,16^3(-1)(x^2)^3*(y^4)^3 )}}}


 {{{root(3,16^3)*root(3,-1^2)*root(3,(x^2)^3)*root(3,(y^4)^3)}}}


 {{{16* root(3,-1^2)*x^2* y^4}}}


 {{{16x^2* y^4* (-1)^(2/3)}}}
