b (2 2/3)^2 = (8/3)^2 = 8/3 razy 8/3 = 64/9
c (- 1 1/2)^3 = (- 3/2)^3 = (-3/2) razy (-3/2) razy (-3/2) = (-27/8)
d (- 2 2/5)^2 = (- 12/5)^2 = (-12/5) razy (-12/5) = 144/25
Odpowiedź:
(1 i 1/4)³ = (5/4)³ = 5/4 * 5/4 * 5/4 = 125/64
(2 i 2/3)² = (8/3)² = 8/3 * 8/3 = 64/9
(-1 i 1/2)³ = (-3/2)³ = (-3/2) * (-3/2) * (-3/2) = -27/8
(-2 i 2/5)² = (-12/5)² = (-12/5) * (-12/5) = 144/25
