Question

Làm tính chia :

a) \(\left(x+y\right)^2:\left(x+y\right)\)

b) \(\left(x-y\right)^5:\left(y-x\right)^4\)

c) \(\left(x-y+z\right)^4:\left(x-y+z\right)^3\)

Answer 1

a)\(\left(x+y\right)^2:\left(x+y\right)=\left(x+y\right)^{2-1}=x+y\)

b)\(\left(x-y\right)^5:\left(y-x\right)^4=\left(x-y\right)^5:\left(-\left(x-y\right)^4\right)=-\left(x-y\right)^{5-4}=-\left(x-y\right)\)

c)\(\left(x-y+z\right)^4:\left(x-y+z\right)^3=\left(x-y+z\right)^{4-3}=x-y+z\)

Answer 2

a)

b)

c)

Answer 3

\(a,\left(x+y\right)^2:\left(x+y\right)=\left(x+y\right)^{2-1}=x+y\)

\(b,\left(x-y\right)^5:\left(y-x\right)^4=\left(x-y\right)^5:\left(x-y\right)^4=\left(x-y\right)^{5-4}=x-y\)

\(c,\left(x-y+z\right)^4:\left(x-y+z\right)^3=\left(x-y+z\right)^{4-3}=x-y+z\)
