Answer 1

j) [(3/5)⁷ : (2- 7/5)⁴ + 5:5/4 - (3/5)³] : 8/5 amplficam pe 2 cu 5

[(3/5)⁷ : (10/5-7/5)⁴ + 5*4/5 - (3/5)³] : 8/5 =

[(3/5)⁷ : (3/5)⁴ + 4 - (3/5)³] :8/5 =

[(3/5)³ + 4-(3/5)³] :8/5 = 4*5/8 = 5/2

k) amplificam pe 1/2 cu 3, pe 2/3 cu 2

[(3/6+4/6+5/6):12/7-109/18]*1/4:(137/25-4/3) amplificam pe 137/25 cu 3 si pe 4/3 cu 25

[2*7/12-109/18]*1/4:(411/75-100/75)=

[7/6-109/18]*1/4:311/75 amplificam pe 7/6 cu 3

[21/18-109/18]*1/4:311/75 =

-8/18*1/4:311/75 = -2/18*75/311= -1/9*75/311= -75/2799= -25/933
