(1)(2)ともにまったく分からないので教えてください!

[大] 大] 重要 例題 9 二項定理の利用 (1) 101 ' の下位5桁を求めよ。 (2)2 00で割った余りを求めよ。 CHART & THINKING のののの 23 基本 (1),(2) ともに, まともに計算するのは大変。 (1) は,次のように変形して、 二項定理を利用する。 1011= (100+1)100= (1+102) 100 展開した後, 各項に含まれる 10 に着目し, 下位5桁に関係する箇所のみを考える。 (2)も二項定理を利用するが,どのようにすればよいだろうか? →900=302 であることに着目し,2930-1 と変形して考えよう。 解答 (1) 1011=(100+1)100= (1+102) 100 =1+100C1・102+100C2・10+100C3・10°+100C4・10°++10200 =1+100C1・102+100C2・10+10%(100Cs+100C4 ・ 102 +... +10194) ここで, a=100C3 +100C4・102 +…+10194 とおくとaは自然数で 101100 = 1+10000 + 49500000 +10°α =10001+49500000 +10°a =10001+105(495+10a) 10 (495+10a) の下位5桁はすべて 0 である。 よって, 101100 の下位 5桁は 10001 (2) 2945(30-1)45=(-1+30)45 =(-1)^5+45Ci (−1)44・30+45C2(-1)43・302+45C3(-1)42・303 ■■ 1章 1 3次式の展開と因数分解,二項定理 分散式は、 +…+45C44(-1)・304+3045 第3項以降の項はすべて 302=900で割り切れる。 また,(-1)45=-1, -1) =1であるから -1+45・1・30=1349=900・1 +449 よって, 2945 を900で割った余りは 449 大←第1項と第2項の和は 900 より大きい。 計算への応用 INFORMATION 上と同じ考え方で, 複雑な計算を暗算で行うことができる。 例えば,9992 は 9992=(1000-1)=1000000-2000+1=998001, 4989×5011 は 4989×5011=(5000-11)×(5000+11)=50002-11=25000000121=24999879 と計算 できる。

【必答問題 5 日常使う物のデザインをする際には標準化 (standardization) という方法がある。 という内容に続く次の英文を読んで、あとの問いに答えよ。(配点44) If we examine the history of advances in all technological fields, we see that some improvements come naturally through the technology itself, while others come through standardization. The early history of the automobile is a good example. The first cars were very difficult to operate. They required strength and skill beyond the abilities of many. Some problems were solved through automation. Other aspects of cars and driving were standardized through the long process of international standards committees: . On which side of the road to drive (constant within countries) country, but variable across On which side f the car the driver sits (depends upon which side of the road the car is driven) -The (2) of essential components: steering wheel, brake, clutch, and accelerator (the same, whether on the left- or right-hand side of the car) Standardization is one type of cultural constraint. With standardization, once you have learned to drive one car, you feel confident that you can drive any car, anyplace in the world. Standardization provides a major breakthrough in usability. I have enough friends on national and international standards committees to realize that the process f determining an internationally accepted standard is laborious. Even when all members agree on the merits of standardization, the task of selecting standards becomes a long, political issue. A small company can standardize its products without too much difficulty, but it is much more difficult for an industrial, national, or international body to agree to standards. There even exists a standardized procedure for establishing national and international standards. organizations works on standards. First, a set of national and international Then when a new standard is proposed, it must work its way through each organization's approval process. Standards are usually the result of a *compromise among the various competing positions, which can often be an inferior compromise. Sometimes the answer is to agree on (4 ). Look at the existence I both metric and *English units; of left-hand- and 18 right-hand-drive automobiles. There are several international standards for the *voltages and *frequencies of electricity, and several different kinds of electrical plugs and sockets- which cannot interchanged. With all these difficulties and with the continual advances in technology, are standards really necessary? Yes, they are. Take the everyday, clock. It's standardized. Consider how much trouble you would have telling time with a backward clock, where the hands revolved "counterclockwise." A few such clocks exist, primarily as humorous conversation pieces. When a clock truly violates standards, such as (the one in Figure 1, it is difficult to determine what time is being displayed. Why? The logic behind the time display is identical to that of conventional clocks: there are only two differences - the hands move in the opposite direction (counterclockwise) and the location of "12," usually at the top, has been moved. This clock is just as logical as the standard one. It. bothers us because we have standardized on a different scheme, on the very definition of the term clockwise. Without such standardization, clock reading would be more difficult: you'd always have to figure out the "mapping.
