Szczegółowe wyjaśnienie:
W pierwszym jest 4/9, bo słabo widać
a)
(2/3)² = 2/3 * 2/3 = 4/9
(- 2/3)³ = (- 2/3) * (- 2/3) * (- 2/3) = - 8/27
(2/3)⁴ = 16/81
(2/3)⁵ = 32/243
(- 2/3)⁶ = 64/729
b)
(2 1/6)² = (13/6)² = 169/36 = 4 25/36
(- 1 1/9)²= (- 10/9)² = 100/81 = 1 19/81
(2 1/7)² = (15/7)² = 225/49 = 4 29/49
(- 1 1/11)² = (- 12/11)² = 144/121 = 1 23/121
(3 1/3)² = (10/3)² = 100/9 = 11 1/9
