也不知道藏没藏哗腔着银芦扮因式分锋灶解

[5xy^2(x^2-3xy)-(-3x^2y^2)^3]/(5xy)^2

=5xy.y(x^2-3xy)-(-3x^2y^2)^2(-3x^2y^2)/(5xy)^2

=yx^2-3xy^2+27x^6y^6/5xy

=xy(x-3y=27x^5y^5)/5xy

=x-3y+27x^5y^5/5

此答案仅供参考

[5xy^2(x^2-3xy)-(-3x^2y^2)^3]/誉伍(5xy)^2

=5xy.y(x^2-3xy)-(-3x^2y^2)^2(-3x^2y^2)/庆耐或(5xy)^2

=yx^2-3xy^2+27x^6y^6/5xy

=xy(x-3y=27x^5y^5)/5xy

=x-3y+27x^5y^5/亩源5
