一番下の最大値4の隣のやつってどーゆー意味ですか？

要例題166 対数関数の最大 最小 (2) OO0O x22, y22, xy=16 のとき、(log2x)(1og2y)の最大値と最小値を求めよ。 基本 162 CHART OSOLUTION 整式と対数が混在した問題 式の形をどちらかに統一 条件 x22, y22, xy=16 と,値を求める (1og2x)(log2y) の式の形が異なるから 扱いにくい。したがって,式の形を統一することから始める。 このとき,(log2x) (log2y) の 1ogを取り外すことはできないから,条件式を対数 の形で表す。条件式の各辺の2を底とする対数をとると log2x2log22, log2y2log22, log2xy=log216 すなわち log2x+log2y=4 よって, log2x=X, log2y= Yとおくと,この問題は X21, Y21, X+Y=4 のとき,XY の最大値 最小値を求める問題 になる。後は 条件式 文字を減らす 変域に注意 の方針による。 解答 x22, y22, xy=16 の各辺の2を底とする対数をとると log2x21, log2y>1, log2x+log2y=4 log2x=X, log2y=Y とおくと Logglos+ log2xy =log2x+log2y X21, Y21, X+Y=4 の また 1og216=1og2 X+Y=4 から Y=4-X Y21 であるから DX21 と合わせて また(log2x)(1og2y)=XY=X(4-X) 消去する文字Yの条件 (Y21)を,残る文字X の条件(X<3) におき換 える。これを忘れないよ うに注意する。 4-X21 ゆえに、X<3 1SX<3 2 =-X°+4X =-(X-2)?+4 f(X)+ 4 3 これをf(X)とすると,② の範囲に おいて,f(X)は X=2 で最大値 4, {01 2 3 4X X=1, 3 で最小値3をとる。 X=2 のとき Y=2, X=1 のとき Y=3, のから 00 X=3 のとき Y=1 log2x=X, log2y=Y より, x=2*, y=2" であるから 16 yの値は y== x から (x, y)=(4, 4) (x, y)=(2, 8), (8, 2) で最小値3 で最大値4; めてもよい。 をとる。
