Dzieki z gory !!!
1.8 i 1/5 - (6 i1/4 - (4 i 1/3 - 2 i 1/2)= 8,2 - (6,25-(4,33 - 2,50)=
= 8,2 - (6,25 - 1,83) = 8,4-4,42 = 3,78
2. 9i1/3 - [ 7 i 1/4- [5 i 1/5 - (3 i 1/6 - 1 i 1/2)=9 i 1/3 - [ 7 i 1/4 -
- [ 5 i 1/5 - 3 i 1/6 - 1 i 3/60= 9 i 1/3 - [ 7 i 1/4 - [ 5 i 1/5 - ( 2 i 7/6 - 1 i 3/6)=
= 9 i 1/3 - [ 7 i 1/4 - [ 5 i 1/5 - 1 i 4/6] = 9 i 1/3 - [ 7 i 1/4 - 5 i 6/30 - 1 i 20/30] = 9 i 1/3 - 3 i 32/43 = 9,33 - 3,74 = 5,59
