zad 2.
a) (-0,2)^3= - 8/1000
b) 2^3:2^4+(-2)*(1/2)^2= 8:16 + (-2)*1/4=1/8-1/2= 1/8-4/8=-3/8
c) (-1 1/3)^-2-(0,1)^-1= (-4/3)^-2-(1/10)^-1=(-3/4)^2-(10/1)^1=9/16-100=-99 16/16=9/16=-99 7/16
d) (-1/3)^2*(-9)=1/9*(-9)=-9

zad 2
a) (-0,3)^3=- 27/100
b) 3^3:3^5+(-3)^2*(1/3)^2= 27:243=9*1/9=1/9+1= 1 1/9
c) (-1 2/3)^-2-(0,1)^-1= (-3/5)^2 -10=9/25-10=-9 16/25
d) (-1/4)^2*(-8)=- 1/16*(-8)=1/2
