4パターン全てでabが3の倍数でない事が分かったから対偶は真だから、もしこの4つのうち1つでも3の倍数になってしまうものが出来たら対偶は偽になりますよね??

基本 例題 60 対偶を利用した証明 (2) 対偶を考えることにより,次の命題を証明せよ。激 ①①①①① 整数 α, bについて, 積αb が3の倍数ならば α または6は3の倍数である。 [東京国際大]基本59 指針 条件の否定 「かつ」 と 「または」 が入れ替わるに沿って,対偶を考える。 ⇒ (g またはr)」の対偶は, 「(g) ⇒ [補足] ab が3の倍数α または6が3の倍数を直接証明するのは, 「abが3の倍 「数」が扱いにくいので難しい。 そこで, 対偶を利用した (間接) 証明を考えてい る。 与えられた命題の対偶は 解答 「a, b がともに3の倍数でないならば, abは3の倍数でない」 である。 a,bがともに3の倍数でないとき, 3で割ったときの余りはそ れぞれ1または2であるから,k,lを整数とすると a=3k+1 または α=3k+2 b=3+1 または 6=31+2 と表せる。 [1] a=3k+1,b=3l+1のとき ab=(3k+1)(31+1)=3(3kl+k+1)+1 3kl+k+1は整数であるから, abは3の倍数でない。 [2] a=3k+1,6=3l+2のとき ab=(3k+1)(3+2)=3(3kl+2k+1) +2 3kl+2k+1は整数であるから, abは3の倍数でない。 [3] a=3k+2,b=3l+1のとき ab=(3k+2)(3l+1)=3(3kl+k+2l) +2 ことに 3kl+k+2lは整数であるから, abは3の倍数でない。 [4] a=3k+2,6=3l+2のとき ab=(3k+2)(3l+2)=3(3kl+2k+21+1) +1 3kl+2k+2l+1 は整数であるから, abは3の倍数でない。 ■ 「αまたは6は3の 倍数である」 の否定 「αは3の倍数 でないかつは3の 倍数でない」 である。 <a=3k±1,6=3l±1 とおいて進めること もできる。 【3×(整数)+1の形 の数は3で割った 余りが1の数で,3 の倍数ではない。 [1]~[4] により, 対偶は真である。 したがって,もとの命題も真である。 GER
