1)
(2³ * 3³ * 5) / (3² * 2³) = 3¹¹ * 5 = 3 * 5 = 15,
2)
(45 * 4²) / (80 * 3³) = (9 * 5 * 4²) / (16 * 5 * 3³)= (3² * 4²) / (4² * 3³)= 1 / 3¹ = 1/3,
3)
(7³ * 2³) / (16 * 49) = (7³ * 2³) / (2⁴ * 7²) = 7¹ / 2¹ = 7/2 = 3 1/2 (или 3,5),
4)
(11 * 9 * 5) / (3³ * 11²) = (11¹ * 3² * 5) / (3³ * 11²) = 5 / (11¹ * 3¹) = 5 / (11 * 3) = 5/33,
5)
(5² * 3³) / (9 * 25) = (5² * 3³) / (3² * 5²) = 3¹ = 3,
6)
(5³ * 29) / (87 * 25) = (5³ * 29) / (29 * 3 * 5²) = 5¹ / 3 = 5/3 = 1 2/3
