Ответ:
1) (a+b)/3a
2) 2/3a^2 * (x-y)
3) a/3(a+b)^2
4) (a-c)/2
5) y-z
6) 2
Объяснение:
1)
3a(a+b)(a+b) / 9aa2(a+b)
3a / 9аa = 1 / 3a
(a+b)(a+b) / (a+b) = (a+b) / 1
1(a+b) / 3a
Ответ: (a+b)/3a
2)
10aab(x-y)(x-y)/15aaaab(x-y)(x-y)(x-y)
10aab / 15aaaab = 2 / 3aa
(x-y)(x-y) / (x-y)(x-y)(x-y) = 1 / (x-y)
2 / 3aa(x-y)
Ответ: 2/3a^2 * (x-y)
4)
3(a-b)(a-c)(a-c) / 6(a-b)(a-c)
3 / 6 = 1 / 2
(a-b) / (a-b) = 1 / 1
(a-c)(a-c) / (a-c) = (a-c) / 1
1 * 1(a-c) / 2 * 1 * 1
Ответ: (a-c)/2
