You can put this solution on YOUR website! [x(x^-3)^6(xy^6xy^-6)^-4y^4] / [(y^4)^5x^-3(y^3)^5]
======================================
[x*x^-18*(x^2)^-4*y^4] / [(y^20)*x^-3(y^15)]
======================================
[x^-17*x^-8*y^4] / [-3x*y^35]
=========================================
[x^-25*y^4] / [-3x*y^35]
=============================
= [-3]/[x^24*y^31]
======================
