Atualização matemáticaAtualização matemática sábado, 01 de março de 2008 (a + b) p ≡ a p + b p (mod p) Lema 1: se p é primo, então: (a + b) p ≡ a p + b p (mod p) Prova: (1) Usando o Teorema Binomial (ver Teorema aqui ), sabemos que: (2) Agora, como p é primo, fica claro que para cada termo p!/(m!)(pm)! , p não é divisível por nenhum termo ≤ m ou por qualquer termo ≤ pm de modo que temos: p!/(m!)(pm)! = p*([(p-1)*...*p-m+1]/[m!]) (3) Isso mostra que cada um desses termos é divisível por p e, portanto: [p!/(m !)(pm)!]a p-m b m Seguidores (73) Próxima Seguir Seguidores Larry Freeman Veja meu perfil completo Sobre mim ► ► 2009 (32) ▼ ▼ 2008 (11) ► ► 19/10 - 26/10 (2) ▼ ▼ 24/02 - 02/03 (3) automorfismo de campo Arquivo do blog mais Criar um blog Login http://mathrefresher.blogspot.com/ http://www.fermatslasttheorem.blogspot.com/2005/09/binomial-theorem.html http://3.bp.blogspot.com/_wqJeUjTB5sE/R8lGvZ8-uFI/AAAAAAAAA6U/16jg2yqV1uM/s1600-h/binomial.png http://www.fermatslasttheorem.blogspot.com/2005/09/binomial-theorem.html http://3.bp.blogspot.com/_wqJeUjTB5sE/R8lGvZ8-uFI/AAAAAAAAA6U/16jg2yqV1uM/s1600-h/binomial.png javascript:nextPage() javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d13482235826396979361\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d10234826637243849537\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d14562053582887229884\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d01988243658842943884\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d17242488963543344500\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d17176464644902390087\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d13040234230849965462\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d16917474849353133555\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d04707255096069856490\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d15684491950812353498\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d08279374304899467468\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d09256386866590449237\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d12416724325090315585\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d13992118574265406312\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d07640544990265123208\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d18160204851545079995\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d08341113007216499059\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d13545938844117806127\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d01991696231614191979\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d15820218169685631403\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/view-follower.g?followerID\x3d03428156999748037772\x26blogID\x3d12604614%22,%20700) javascript:openPopup("https://www.blogger.com/follow.g?view\x3dFOLLOW\x26blogID\x3d12604614%22,300) https://www.blogger.com/profile/06906614246430481533 https://www.blogger.com/profile/06906614246430481533 https://www.blogger.com/profile/06906614246430481533 javascript:void(0) http://mathrefresher.blogspot.com/2009/ javascript:void(0) http://mathrefresher.blogspot.com/2008/ javascript:void(0) http://mathrefresher.blogspot.com/2008_10_19_archive.html javascript:void(0) http://mathrefresher.blogspot.com/2008_02_24_archive.html http://mathrefresher.blogspot.com/2008/03/field-automorphism.html https://www.blogger.com/ https://www.blogger.com/home#create https://www.blogger.com/ 25/01/2023 12:16 Atualização matemática: (a + b)p ≡ ap + bp (mod p) mathrefresher.blogspot.com/2008/03/b-p-p-b-p-mod-p.html 2/3 Postado por Larry Freeman às 4h01 ≡ 0 (mod p) (4) Então existe um inteiro n tal que: (a + b) p = a p + np + b p (5) Visto que a p + nb + b p ≡ a p + b p (mod p) , segue que: (a + b) p ≡ a p + b p (mod p) QED 2 comentários: Desconhecido disse...
