Răspuns:
A doua paranteza dreapta e 1 fiindca exponentul e 0>Nu mai trebuie facute calculele
[2,5/9-2,(3)]*(11/32:22/20-3/48)=
[2,5/9/-2.3/9)*(11/32*20/22-3/48)=
(5-3)/9*(1/32*20/2-1/16)=
2/9(1/32*10-1/16)=
2/9*(5/16-1/16)=
2/9*(4/16-1/16)=
2/9*3/16=
2/3*1/16=1/3*1/8=1/24
Adui cu 1 de la a 2-a paranteza
1/24+1=25/24
