Сократительной дробь t^2-36/6+t 9+12z+16z^2/27-64z^3 27a^3+8/2+3a

1)

(t² - 36) / (6 + t) = ((t - 6) * (t + 6)) / (t + 6) = (t - 6).

2)

(9 + 12 * z + 16 * z²) / (27 - 64 * z³) = (9 + 12 * z + 16 * z²) / ((3 - 4 * z) * (9 + 12 * z + 16 * z²)) = 1 / (3 - 4 * z).

3)

(27 * a³ + 8) / (2 + 3 * a) = ((3 * a) ³ + 2³) / (2 + 3 * a) = ((3 * a + 2) * (9 * a² + 6 * a + 4)) / (2 + 3 * a) = (9 * a² + 6 * a + 4).
