1) 3a - 27/4a-36
в числителе выноси общий множитель 3 а в знаменателе 4
и будет 3(а - 9)/4(а - 9) и то что в скобках сокращаем (потому что оно одинаковое) = 3/4
2) 11(d+6)^8 / 88(d+6) = (d+ 6)^8/8
4) Приведи дроби x^2 / x^2−u2 и x−u / 7x+7u к общему знаменателю.
5. 7x^2 / 7(x+u)(x−u) и x^2−2xu+u^2 / 7(x+u)(x−u) (правильный)
5) 3x / x−11 и 8y / x+11
4. 3x^2+33x / x^2−121 и 8yx−88y / x^2−121 (правильный)
Сократите дробь 5m+an−5n−am / a^2−10a+25 до знаменателя 5−a
5m+an−5n−am / a^2−10a+25 = (5 - а)(m - n)/(5 - a)^2 = m - n/ 5 - a
