数学II　指数対数 ピンクの付箋のところの1行上からの右辺の変形が分かりません。log a a　が1になるのに1はどこに行ったんですか？

194 第11章 指数関数・対数関数 基本例題 84 対数不等式 (1) 不等式 10g(x-3)-10g/x-1>0の解は (POINT ! 対数不等式 → まず (数) > 0 loga M loga Nのとき α >1 解答 真数は正であるから x-3> 0, x>0 共通範囲を求めて x>3 よって 1 不等式から 10g(x-3)>log/x+10g 2 log/(x-3)> 10g/1x 1742 1 底 1/23は1より小さいから x-3< xC 2 よって x < 6 ① ② から 3 <x<6 ならば MN 0<a<1 ならば MON (83) ...... ...... - ア<x<イである。 3 6 CHART まず (数) > 0 基 78 3 0<a<1のとき不等号の 向きが変わる。 参考 この問題では,10gxと1を右辺に移項して解いた。移項せずに解くと、 At log/(x-3)-10g/x-1=10g/ と分数式が出てきてしまい煩雑である。 x-3 1 2x 対数方程式・不等式では,係数が負の項を移項して解くとよい。

After his illness, Caligula began torturing and putting to death huge numbers of citizens for even minor offenses. He also claimed to be a living god. These actions may suggest mental instability, but another explanation is that they were intended to secure his position.

In the United States, safety regulations are ( 30 ). Although some vehicles have become larger and their shape has changed, laws have not changed to reflect the increased danger they pose to pedestrians. Critics say that regulating only the safety of vehicle occupants is irresponsible, and that pedestrian deaths have increased even though there are simple measures that could be taken to help prevent them.
