[tex] \frac{a}{10} + \frac{aa}{100} + \frac{aaa}{1000} =2,568[/tex]
si acuma scriem numerele sub forma zecimala: [tex] \frac{a}{10} + \frac{10a +a}{100}+ \frac{100a +10a+a}{1000} = 2,568[/tex]
[tex] \frac{a}{10} ^{100} + \frac{11a}{100} ^{10} + \frac{111a}{1000} = 2,568[/tex]
[tex] \frac{100a+110a+111a}{1000} =2,568^{1000} [/tex]
[tex]a(100+110+111)=2568[/tex]
