Question 697583
{{{((12x^(-3))/(y^4))*(((y^(-2)x^(2))^(-4))/(15x^(-2)))}}}



{{{((12/x^3)/(y^4))*((((1/y^2)x^2)^(-4))/(15/x^2)))}}}


{{{(12/(x^3y^4))*((((x^2/y^2))^(-4))/(15/x^2)))}}}


{{{(12/(x^3y^4))*((1/(x^2/y^2)^4)/(15/x^2)))}}}


{{{(12/(x^3y^4))*((x^2/15(x^8/y^8)))}}}


{{{(12/(x^3y^4))*((x^2y^8)/15x^8))}}}


{{{(cross(12)4/(x^cross(3)^1cross(y^4)))*((cross(x^2)y^cross(8)^4)/cross(15)5x^8))}}}



{{{(4*y^4)/5x^9}}}
