Resposta da questão 9: Calculando: ????( ????) = ???? ⋅ ????0 ⋅ ????????⋅???? ???? + ????0(???? ????⋅????−1) ????(1) = ????0 ⋅ ???????? → 5 ⋅ 10−2 = 20 ⋅ ???????? 2 ⋅ 109 + 20???????? −20 5 ⋅ 10−2 ⋅ (2 ⋅ 109 + 20???????? −20) = 20 ⋅ ???????? 108 + ???????? −1 = 20???????? → 108 − 1 = 19???????? → ???????? = 108 − 1 19 ???? = ???????????????? ( 108−1 19)
