Kodi muzu lalikulu?

Mwa kuika nzeru, zomwe ndi chizindikiro cha kulemba mu malo oyamba ndi zilembo. Kenako, yemweyo "kwambiri" amafotokozera ndi luso Kuwonjezera-chulutsa ndi pafupi iwo, koma tanthauzo n'zosiyana, masamu wochotsera, magawano. Tiphunzire luso akutali ubwana sukulu, kutumikira mokhulupirika usana ndi usiku: TV, nyuzipepala, SMS inivoyisi. Ndipo kulikonse, ife kuwerenga, kulemba view, kuwonjezera, kuchotsera, chulukanani. Ndipo undiuze kangati muli moyo, kuchotsa mizu, kupatula mu dziko? Mwachitsanzo, ngati ntchito ndimasewera, monga, muzu lalikulu la nambala 12345 ... Pali moyo galu wamkulu? Katswiri? Inde, palibe mosavuta! Ali Chiwerengero changa ... Ndipo popanda dzanja m'manja, pang'ono?

Choyamba, tiyeni mwachindunji ndi zimene - muzu lalikulu angapo. Kunena zoona, "kuchotsa mizu lalikulu la chiwerengero" amatanthauza kuchita masamu ntchito zosiyana exponentiation - ndicho inu ndi umodzi wa zotsutsana mu moyo ntchito. Exponentiation, tiyeni tinene, apakati, ndi chulutsa chiwerengero payokha, ie, ankaphunzitsa ku sukulu, X * X = A kapena zolemba zina X2 = A, ndi mawu - "X lofanana mbali zonse ndi wofanana A". Ndiye vuto osiyanitsidwa ndi: muzu lalikulu la A, X ndi nambala imene akugwiritsa anamangidwira pabwalopo ali wofanana A.

Kuchokera Maphunziro a njira masamu amadziwika kompyuta "mu ndime ya" thandizo kuchita kuwerengetsera aliyense ntchito woyamba anayi ntchito arithmetical. Kalanga ... Kuti lalikulu, osati mizu lalikulu la ma aligorivimu izi kulibeko. Ndipo mu nkhani iyi, ngati muzu lalikulu popanda Chiwerengero? Yachokera pa tanthauzo la apakati muzu linanena bungwe - m'pofunika kusankha zotsatira mtengo manambala chakuthengo mphamvu amene lalikulu wakudza mtengo wa radicand lapansi. Ndizo zonse! Alibe nthawi pochitika ola limodzi kapena awiri, monga n'zotheka kuwerengera ntchito njira odziwika a chulutsa mu "mzati" wa muzu wina lalikulu. Ngati ndinu omasuka tigwile angapo Mphindi. Ngakhale si zapamwamba kwambiri wosuta Chiwerengero kapena PC zimapangitsa izo mu umodzi utagwa Sinthani - patsogolo.

Koma kwambiri, muzu lalikulu kawirikawiri anachita ntchito njira "zida zankhondo mafoloko": oyambirira angapo amene lalikulu, ziri limafanana ankafuna kusintha zinthu mopitirira ndi. Ndi bwino ngati "lalikulu wathu" zosakwana mawu amenewa. Kenako, kusintha chiwerengero cha luso lawo, kumvetsa Mwachitsanzo, kuchulukitsa ndi awiri, ndi ... kachiwiri lofanana mbali zonse. Ngati chifukwa ndi wamkulu kuposa chiwerengero pansipa muzu successively kukonza nambala choyambirira pang'onopang'ono kuyandikira ake "mnzake" pansi muzu. Monga mukuonera - palibe Chiwerengero okha luso tikambirana "mu mzati". Kumene, pali zambiri sayansi natsutsana ndi wokometsedwa ma aligorivimu kwa kompyuta mizu lalikulu, koma "ntchito kunyumba" madyedwe pamwamba amapereka 100% chidaliro mwa zotsatira zake.

O, ine pafupifupi anaiwala kuti atsimikizire kulemba ake kuchuluka, kuwerengera muzu lalikulu la nambala kale mwachindunji 12345. Pangani sitepe ndi sitepe:

1. Tengani intuitively, X = 100. Ife kuwerengera: X * X = 10,000 yodziŵiratu zinthu pasadakhale pa kutalika - zotsatira ndi zosakwana 12345.

2. Yesani komanso intuitively, X = 120.: X * X = 14400.I kachiwiri ndi kuti yodziŵiratu zinthu pasadakhale - chifukwa cha kuposa 12345.

3. pamwambapa adalandira "foloko" 100 ndi 120. Sankhani nambala yatsopano - 110 ndi 115. Ife tilandire, motero, 12100 ndi 13225 - foloko itsekeke pang'ono.

4. Yesani "mwachisawawa" X = 111. * Pezani X X = 12321. chiwerengero Izi pafupi mokwanila 12345. Mogwirizana ndi lolondola chofunika "woyenera" mukhoza kupitiriza kapena kusiya zotsatira analandira. Ndizo zonse. Monga analonjeza - zonse ndi lophweka ndi opanda Chiwerengero.

Pang'ono za mbiri ...

Iwo anagunda pa lingaliro ntchito mizu lalikulu akadali Pythagoreans ophunzira sukulu ndi otsatira a Pythagoras, 800 BC ndiyeno "anathamangira" chifukwa cha zimene anatulukira latsopano m'munda wa manambala. Ndipo kodi kuti anachokera kuti?

1. Njira yothetsera vuto ndi kuchotsa mizu, amapereka zotsatira mu mawonekedwe a latsopano kalasi ya manambala. Iwo ankatchedwa zopanda nzeru, ndiko kunena kuti, "wopanda nzeru" chifukwa iwo sizilembedwa chiwerengero chokwanira. Chitsanzo kwambiri powerenga za mtundu uwu - muzu lalikulu la 2. mlanduwu unali wolingana ndi mawerengedwe a opendekera wa apakati ndi mbali wofanana 1 - kutanthauza kuti mphamvu ya sukulu ya Pythagoras. Kunapezeka kuti kansalu ndi kukula kwenikweni mbali imodzi, ndi hypotenuse cha kukula kuti chimaoneka ndi chiwerengero chabe, imene "sikudzatha." Choncho masamu anaonekera manambala zopanda nzeru.

2. amadziwika kuti mgugu mavuto anayamba. Kunapezeka kuti ntchito imeneyi masamu lili tsenga wina - kutengera muzu lalikulu, ife sitikudziwa m'bwalo la nambala zabwino kapena zoipa, ndi kwakukulu mawu. njakata ichi, chifukwa awiri a ntchito imodzi, ndipo analemba.

Phunziro kugwirizana ndi nkhawa imeneyi chodabwitsa anali zochokera mu masamu, wotchedwa chiphunzitso cha variable zovuta, zomwe ndi zofunika kwambiri zothandiza sayansi masamu.

Modabwitsa, zoti wa muzu - ndi - ntchito yake "masamu Universal" ndi chimodzimodzi ubiquitous Newton, ndipo masiku ano tione chimodzimodzi kapena kungosunga muzu wakhala kuyambira 1690 m'buku France Rolle "Kutsogolera ajebura".
