Làm tính chia:
1. (-2x4 + 5x2y - 4x2y2) : (-2)
2. (4x3y - 16x2y2 - xy3) : (-\(\frac{4}{3}\))
3. (4x3 - 3x2y + 5xy2) : \(\frac{1}{2}\)x
4. (2x4 - x3 + 3x2) : (-\(\frac{1}{3}\)x2)
5. (18x3y - 12x2y2 + 6xy3) : 6xy
6. (\(\frac{3}{4}\)x3y6 + \(\frac{6}{5}\)x4y3 - \(\frac{9}{10}\)x5y) : \(\frac{3}{5}\)x3y
7. [3(x - y)5 - 2(x - y)4 + 3(x - y)2 ] : 5(x - y)2
Tính
a) \(\frac{3}{4}x^5y^7\) : \(\left[\frac{1}{2}x^2\left(y-1\right)^2\right]\)
b) -x2 (y - 1)3 (z + 2)2 : [ \(\frac{1}{2}\)x2 (y - 1)2 ]
\(\frac{3.x^5\left(4x^2+5\right)^2}{\left(4x^2+5\right)^2}-\frac{x\left(3x^4+7\right)^2}{3x^4+7}=2x-5\)

b,[5(x - y)mũ 4 - 3(x -y)mũ 3 + 4(x -y)mũ 2] : (y - x)mũ 2
c,[(x+y)mũ 5 - 2(x+y)mũ 4 + 3(x+y)mũ 3] : [-5(x+y)mũ 3]
bài 1: Thực hiện phép chia

b, 4 ( x + y )3 : 2 ( x + y )
c, ( 8x3 + 27y3 ) : ( 2x + 3y )
d, ( 48 x4 y3 - 12x2y5 + 6x2y2 ) : ( 3x2y2 )
cho \(\frac{1}{x}+\frac{1}{y}+\frac{1}{z}\)=0
chứng minh rằng: (x2y2+y2z2+z2x2)2=2(x4y4+y4z4+z4x4)
