Odpowiedź:
d) (-1,1)^2 = 2.1
(1 i 1/4)^3 = (5/4)^3 = 125/64 = 1 i 61/64
(-2 i 1/5)^3 = (-11/5)^3 = -1331/125 = -10 i 81/125
1.3^2 = (13/10)^2 = 169/100 (1,69)
e) -3^4 = 81
-(-1.5)^3 = -(-3/2)^3 = 27/8 = 3 i 3/8
-1.1^2 = -2.1
-(-2/3)^4 = -16/81
f) 2^3/3 = 8/3 = 2 i 2/3
(-3)^2/ 2 = 9/2 = 4 i 1/2
2/3^2 = 2/9
-5^3/(-3)^2 = -125/9 = -13 i 8/9
