(-3xy^2)^2+(-4xy^3)*(-xy)=多少
(-3xy^2)^2+(-4xy^3)*(-xy)=多少
(-3xy^2)^2+(-4xy^3)*(-xy)=多少
(-3xy^2)^2+(-4xy^3)*(-xy)=
=9x²y^4+4x²y^4
=13x²y^4
(-3xy+2xy)-(4xy+xy)
3xy-4xy-(-2xy)
3xy-4xy-(-2xy)
3xy-3xy-xy+2yx
2xy.(-3xy)÷(xy)
2xy-xy-(-3xy)=
(-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)
计算-xy-(4z-2xy)-(3xy-4z)
-xy(4z-2xy)-(3xy-4z) 化简
计算:3xy-4xy-(-2xy)要过程
(1)3xy-4xy-(-2xy)
3xy-4xy-(-2xy)的解法
3xy-4xy-(-2xy) 快啊,亲
[(2xy-3)(2xy+3)+(xy+3)^2]/(-xy)
xy-3xy+2xy-xy
