you may take each thing contained in the parentheses to the exterior potential. do not calculate some thing till the very end. once you've executed that then some thing that has a detrimental exponent could could modify aspects from the acceptable to the bottom and finally end up efficient. Then multiply or divide the efficient exponents as you many times could.

=(1/(-6^3x^3y^-12)/1/(x^8y^-16)
=(1/(-6^3x^3y^-12)(x^8y^-16)
=- x^5y^4/216
