-(-4xy^2)^3(-y^3)^5-(-4xy^2)^3(-y^3)^5-(-4xy^2)^3(-y^3)^5-(-4xy^2)^3(-y^3)^5=-(-64x^3y^6)(-y^15)=-64
-(-4xy^2)^3(-y^3)^5
-(-4xy^2)^3(-y^3)^5
-(-4xy^2)^3(-y^3)^5
-(-4xy^2)^3(-y^3)^5
=-(-64x^3y^6)(-y^15)
=-64x^3y^21
^这个是乘以的意思么
解原式=-(-8xy)^-3y^9^5
=8xy^-3y^45
=-24xy*^45
=-1080xy* (*是平方的意思)
-(-4xy^2)^3(-y^3)^5
= - (-4^3x^3y^6)(-y^15)
= - 64x^3y^21
3x^2y^2-[5xy^2-(4xy^2-3)+2x^2y^2,其中x=-3,y=2
3x^2y^2-[5xy^2-(4xy^2-3)+2x^2y^2,其中x=-3,y=2
已知7 x^2 + 5y x^2=12xy,并且xy不等于0,则可求出()的值(1)xy(2)x/y(3)x+y(4)x-y为什么?
已知x^2y等于3,求2xy(x^5y^2-3x^3y-4x)
化简.x^2-3xy/x^2-6xy+9y^2
-(-4xy^2)^3(-y^3)^5
-(-4xy^2)^3(-y^3)^5要过程
化简:5根号X^3Y-2Y根号XY-6根号XY+根号X分之Y+根号Y分之X
4X^2-12XY+9Y^2-2X+3Y-6化简!
3(x^4)^3-2(xy)^4x^8y+5(x^3y^2)x^6y
x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
5x^2y-3xy^2+4xy-14xy^2+4xy-2x^2y(化简)
计算:5xy^2-[3xy^2-(4xy^2-2x^2y)]+2x^2y-xy^2
5xy^2-(3xy^2-(4xy^2-2x^2y))+2x^2y-xy^2求
若X^2+XY=2,XY—Y^2=-7,则X^2+Y^2=( );X^2+3XY-2Y^2=( )
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
