Answer 1

9
г)((x+y)^5/[(x+y)^8*(x-y)]=1/[(x+y)³(x-y)]
д)(2z-5)(2z+5)/(2z-5)²=(2z+5)/(2z-5)
е)3h²j^4(2x+5)/(2x+5)³=3h²j^4/(2x+5)²
10
д)(a²-b²)/(a³-b³)=(a-b)(a+b)/[(a-b)(a²+ab+b²)]=(a+b)/(a²+ab+b²)
е)(g+h)²/(g³+h³)=(g+h)²/[(g+h)(g²-gh+h²)]=(g+h)/(g²-gh+h²)

Answer 2

№9
г)((x+y)^5/(x+y)^8*(x-y)=1/(x+y)^3(x-y)
д)(2z-5)(2z+5)/(2z-5)^2=(2z+5)/(2z-5)
е)3h^2j^4(2x+5)/(2x+5)^3=3h^2j^4/(2x+5)^2
№10 не знаю как))))
