Pq p, FGV! Para tudoo Porque o que a FGV fez aqui é um absurdo. Ela pega isso aqui: 25⁶⁴ · 64²⁵ e diz que isso é o quadrado de um número inteiro x. Até aí… ok. Mas agora vem a maldade. Ela quer a soma de TODOS, eu disse T O D O S os algarismos de x. Sério. A primeira reação da maioria dos alunos é pensar: não é possível que eu vou ter que calcular um número gigantesco só pra depois sair somando dígito por dígito. Mas aqui vai uma coisa que quase ninguém percebe nas provas
