a) (3/2)^2 - (1/2)^4 = 9/4 - 1/16 = 36/16 - 1/16 = 35/16 = 2 i 3/16
b) (4/3)^2 - 8/27 = 16/9 - 8/27 = 48/27 - 8/27 = 40/27 = 1 i 13/27
c) (3/2)^3 + (3/4)^2 = 27/8 + 9/16 = 54/16 + 9/16 = 63/16 = 3 i 15/16
d) 1/49 - 25 = - 24 i 48/49
e) (5/3)^2 + (1/6)^2 = 25/9 + 1/36 = 100/36 + 1/36 = 101/36 = 2 i 29/36
f) (7/8)^2 - (3/4)^3 = 49/64 - 9/16 = 49/64 - 36/64 = 13/64
