Question

Giúp mk câu g,h,i bài 1;bài 2 nhé

Answer 1

a) -28xy⁵z³ : 7xy²z³= -4y³

b) 8x²y²z : 6xyz= 6xy

 

Answer 2

c) 6x³y⁴ : x³y=6y³

d) 30x²y²z: 6xyz

e) 54x⁴y²z: 9x⁴y= 6y³z

Answer 3

f) x⁴y³z² : 3xyz²= \(\dfrac{1}{2}\)x³y²

g) (x+y)⁵: (x+y)⁴= (x+y)¹= x+y

h) (x-y)⁷ : (y-x)⁶ = -(y-x)⁷: (y-x)⁶= -(y-x)¹= -(y-x) = -y +x

i) (x-y+z)⁵ : (x-y+z)⁴ = (x-y+z)¹= (x+y-z)= x+y-z
