7\5+0.(81)+3^2•(5-4•1\8)=7\5+81\990+9•(5-4\1•1\8)=7\5+9\110+9•(5-1\1•1\2)=7\5+9\110+9•(5-1\2)=154\110+9\110+9•(5\1-1\2)=163\110+9•(10\2-1\2)=32,6+9•9\2=32,6+18\2=32,6+9=41,6
Sper că te-am ajutat.(⊙o⊙)

= 7/5 + 0,(81)+9•(5-1/2) = 1,(4)+0,(81)+ 9•(10/2-1/2) = 2,(21)+9•(9/2) = 2,(21)+81/2 = 2,(21)+40,(5) = 42,(71)
