A notação 2e11 significa 2 * 10^11, onde o ^ significa "elevado a". Ou
seja, traduzindo, o que o Rafael disse foi:

Escrevendo 99999899999 como 10^11 - 10^5 - 1, temos que:

(99999899999)^2 = (10^11 - 10^5 - 1)^2
= 10^22 - 10^16 - 10^11 - 10^16 + 10^10 + 10^5 - 10^11 + 10^5 + 1
= 10^22 - 2*10^16 - 2*10^11 + 10^10 + 2*10^5 + 1

Desculpe Rafael, não estou conseguindo entender legal esse começo:

escrever 99999899999 como 1e11 - 1e5 - 1, ao quadrado isso vale:

1e22 - 2e16 - 2e11 + 1e10 + 2e5 + 1. e daí para frente eu nem continuei ...tens como me ajudar ?
