Ser\u00e1 que consegues descobrir o valor de x?<\/p>\n\n\n\n

Sabemos que:<\/p>\n\n\n\n

x = 0,999999999…<\/p>\n\n\n\n

Ent\u00e3o:<\/p>\n\n\n\n

10x = 9,999999999…<\/p>\n\n\n\n

Agora subtra\u00edmos:<\/p>\n\n\n\n

10x – x = 9,999999999… – 0,999999999…<\/p>\n\n\n\n

Logo:<\/p>\n\n\n\n

9x = 9<\/p>\n\n\n\n

Ent\u00e3o:<\/p>\n\n\n\n

x = 1<\/p>\n\n\n\n

Como explicarias a um colega que 0,999999999… \u00e9 igual a 1, mesmo parecendo que falta \u201cum bocadinho\u201d?<\/p>\n\n\n\n
