Odpowiedź:
a)
(-4)²/8² = (-4/8)² = (-1/2)² = 1/4
0,55²/0,11² = (0,55/0,11)² = 5² = 25
121²/11² = (121/11)² = 11² = 121
(-4,8)^6 : (-4 4/5)^6 = (-4,8)^6 : (-4,8)^6 = 1^6 = 1
b)
(-2,56)³ : (16/25)³ = (-2,56)³ : (0,64)³ = 4³ = 64
(-0,9)² : (3/8)² = (-0,9)² : (0,375)² = (-0,9/0,375)² = (-2,4)² = 5,76
(1 2/3)^4 : (-2 7/9)^4 = (-5/3 : 25/9)^4 = (-5/3 * 9/25)^4 = (-3/25)^4 =
(-0,12)^4 = 0,00020736
