Zad 1
a) 2^3 = 2•2•2 = 8
b) 6^2 = 6•6 = 36
c) (-4)^2 = (-4)•(-4) = 16
d) (-2)^3 = (-2)•(-2)•(-2) = -8
e) (1/3)^3 = 1/3•1/3•1/3 = 1/27
f) (2/5)^4 = (2/5)•(2/5)•(2/5)•(2/5) = 16/625
g) (5/4)^2 = 5/4•5/4 = 25/16 = 1 9/16
h) (-3/7)^2 = (-3/7)•(-3/7) = 9/49
i) (-2/10)^3 = (-2/10)•(-2/10)•(-2/10) = -8/1000 = -1/125
