Explicație pas cu pas:

{[2 si 1/3 - 0,(3)]³ :[19/10:0,12 +0,8(3)]+0,12}·5 =

= {[(2·3+1)/3 - 3/9]³:[19/10 ·100/12 +(83-8)/90] + 12/100}·5 =

= {[7/3-1/3]³:[¹⁵⁾190/12 + ²⁾75/90] + 12/100}·5 =

= {[6/3]³:[(2850+150)/180] + 12/100}·5 =

= {2³:[3000/180] + 12/100}·5 =

= {8 · 180/3000 + 12/100}·5

= (48/100 + 12/100)·5 =

= (60/100 )·5 = 300/100 = 3
