Question

化简：[x(x^3y^2)^2-2(x^2y)^3+3](xy^2)^3

(a^2-2b)(a^2+3b)-3a^2(a^2+2b)+(5a^2-2b)(-2b-5a^2)+26a^4、化简

Answer 1

[x(x^3y^2)^2-2(x^2y)^3+3](xy^2)^3
=[x^7y^4-2x^6y^3+3](x^3y^6)
=x^10y^10-2x^9y^9+3x^3y^6

Answer 2

=(x×x的6次方y的4次方-2x的6次方y³+3)×(x³y的6次方)
=(x的7次方y的4次方-2x的6次方y³+3)×(x³y的6次方)
=x的10次方y的10次方-2x的9次方y的9次方+3x³y的6次方
