Zad.1
a) 4 i3/20 -1,9 = 4,15 -1,9 = 2,25
b) 93i3/5 : 0,13 = 93,6 : 0,13 = 720
c) 4,19 + 1i3/25 = 4,19 + 1,12 = 5,31
d) 5 i7/16 * 1000 = 5,4375 * 1000 = 5437,5
Zad.2
a) 5/6 *0,42 +1,3 * 2i2/1 = 5/6 *21/50 +13/10* 4/1 = 1/2 *7/10 +13/5 *2 =

c) 3,6 * (3/4 +2/3)= 3i3/5 *(9/12 + 8/12)= 18/5 * 17/12= 3/5 *17/2=51/10= 5i1/10
d) 2i1/4 *1i1/3 -2,128= 9/4 *4/3 -2i16/125 = 3/1 *1/1 -2i16/125= 3 -2i16/125 =
= 2 i 125/125 - 2 i16/125 = 109/125
e) (2/3 -0,5) = ( 2/3 - 1/2 ) = 4/6 - 3/6 = 1/6
f) (1 i1/2)^2+(2,3)^2 =(3/2)^2+ (23/10)^2 = 9/4 + 529/100= 225/100 +529/100 =
= 754/100 = 7 i54/100 = 7 i 27/50
