zad.1 sześcian liczby 1 1/2: zad.2 oblicz:(1 5/12+0,5)*(6 2/5-4,9)=
1 1/2= 3/2
(3/2)³= 27/8
zad.2
(1 5/12 + ½)* (32/5- 49/10)=
(17/2+ 1/2)* (64/10-49/10)=
(18/2)*(15/10)= 9*3/2= 27/2= 13 ½
1) (1 i1/2)³=(3/2)³=27/8=3i3/8
2) (1 i5/12+0,5)(6 i2/5-4,9)=(1 i5/12+6/12)·(6,4-4,9)=1 i11/12·3/2=23/12·3/2=
=69/24= 23/8=2 i7/8
