Question

Решите пожалуйста)....

Answer 1

А
x(y-7)/y(y-7)=x/y
б
(10a-15b)/(16a-24b)=5(2a-3b)/8(2a-3b)=5/8
в
(2m+14)/(m²-49)=2(m+7)/(m+7)(m-7)=2/(m-7)
г
(p²-25q²)/(2p-10q)=(p-5q)(p+5q)/2(p-5q)=(p+5q)/2
д
(x²-4x+4)/(x²-2x)=(x-2)²/x(x-2)=(x-2)/x
е
(3y²+24y)/(y²+16y+64)=3y(y+8)/(y+8)²=3y/(y+8)
ж
(a²+a+1)/(a³-1)=(a²+a+1)/(a-1)(a²+a+1)=1/(a-1)
з
(b+2)/(b³+8)=(b+2)/(b+2)(b²-2b+4)=1/(b²-2b+4
