Răspuns: [tex]\bf \red{\underline{10}}[/tex]
Explicație pas cu pas:
[tex]\bf 3\cdot3 + \{9\cdot [6 - (8 + 2 \cdot 6): 5] -8\} : 10 =[/tex]
[tex]\bf 3\cdot3 + \{9\cdot [6 - (8 + 12): 5] -8\} : 10 =[/tex]
[tex]\bf 3\cdot3 + [9\cdot (6 - 20: 5) -8] : 10 =[/tex]
[tex]\bf 9 + [9\cdot (6 - 4) -8] : 10 =[/tex]
[tex]\bf 9 + (9\cdot 2 -8) : 10 =[/tex]
[tex]\bf 9 + (18 -8) : 10 =[/tex]
[tex]\bf 9 + 10 : 10 =[/tex]
[tex]\bf 9 + 1= \red{\underline{10}}[/tex]
