【(-2xy*4)*2】*3
【(-2xy*4)*2】*3
【(-2xy*4)*2】*3
【(-2xy*4)*2】*3
=【4x²y的8次方】³
=64x的6次方y的24次方
3xy-4xy-(-2xy)
3xy-4xy-(-2xy)
(-3xy+2xy)-(4xy+xy)
(-4xy^3)×(-xy)+(-3xy^2)^2
计算:3xy-4xy-(-2xy)要过程
(1)3xy-4xy-(-2xy)
(X-3xy+4xy-y)-[-2x-2(xy-3/2xy)-y]+6xy的过程
计算:3xy-4xy-(-2xy)3xy-4xy-(-2xy)-1/3ab-1/4a²+1/3a²-(-2/3ab)
(-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
3xy-4xy-(-2xy)的解法
3xy-4xy-(-2xy) 快啊,亲
(3xy²)*(-2xy)
5x^2y-3xy^2+4xy-14xy^2+4xy-2x^2y(化简)
化简 2(xy-xy²+3)-(-4xy²+xy-1) 其中,x等于--4,y等于-3
