5xy^2-[3xy^2-(4xy^2-2x^y)]+x^2y-xy^2如何化简如何化简,
5xy^2-[3xy^2-(4xy^2-2x^y)]+x^2y-xy^2如何化简
如何化简,
5xy^2-[3xy^2-(4xy^2-2x^y)]+x^2y-xy^2如何化简如何化简,
5xy^2-[3xy^2-(4xy^2-2x^y)]+x^2y-xy^2
=5xy^2-3xy^2+(4xy^2-2x^y)+x^2y-xy^2
=5xy^2-3xy^2+4xy^2-2x^y+x^2y-xy^2
=5xy^2-x^2y
(-3xy+2xy)-(4xy+xy)
3xy-4xy-（-2xy）
3xy-4xy-（-2xy）
3xy-3xy-xy+2yx
1.3xy -4xy-(2xy)
2xy.(-3xy)÷(xy)
2xy-xy-(-3xy)=
[(2xy-3)(2xy+3)+(xy+3)^2]/(-xy)
xy－3xy＋2xy－xy
(-4xy^3)×（-xy）+（-3xy^2）^2
（-3xy^2)^2+(-4xy^3)*(-xy)=多少
(-4xy^3)*(-xy)+(-3xy^2)^2
(3xy^2)^2+(-xy^3)(4xy)
3xy^2*(-2xy)
2xy(5xy的2次方+3xy-1)
2xy(5xy的2次方+3xy-1)
计算-xy-(4z-2xy)-(3xy-4z)
-xy(4z-2xy)-(3xy-4z) 化简
