He aha te mea te pakiaka tapawha?

I roto i te huinga o te matauranga, i te mea he tohu o te reo matatini i roto i te wahi tuatahi ko te tātai reta. Next, i roto i te taua "nui" huānga ko te pūkenga tua-whakarea me te pātata ki a ratou, engari ko te tikanga whakamuri, tangohanga tauhanga, wehenga. Lēsoni i roto i nga pūkenga kura kōhungahunga tawhiti, mahi pono ra, me te po: TV, niupepa, SMS nama. A i nga wahi katoa, tai'o tatou, tuhituhi, tirohanga, tāpiri, tango, tini. Na, korero mai ki ahau, me pehea maha e whai koe ki te ora, te tango i nga pakiaka, anake rite i roto i te whenua? Hei tauira, he taua mahi whakangahau, pērā i, te pakiaka tapawha o te tau 12345 ... He he ora i roto i te kuri tawhito? Taukei? Ae, i reira he mea māmā! Kei hea ko toku tātaitai ... A kahore reira, ki te ringa ringa, iti?

Tuatahi, kia whakapūtā tatou he aha te mea te reira - te pakiaka tapawha o te tau. Te tikanga e korero, "ki te unu i te pakiaka tapawha o te tau" tikanga ki te mahi i te mahi tauhanga taupūtanga ritenga - e te koutou me te kotahitanga o fehangahangaí i roto i te tono i te ora. Taupūtanga, kia mea a, he tapawha, ko te whakarea o te tau i tahaki, arā, kia rite ki whakaako i te kura, X * X = A ranei te tahi atu ngā tāurunga X2 = A, me nga kupu - "tapawha X he rite ki te". Katahi te raruraru kōaro ko: te pakiaka tapawha o te, X Ko te maha e kei te whakaturia i roto i te tapawha te rite ki te A.

pakiaka Tapawhā

Mai i kei te mohiotia te akoranga kura o tikanga tātai rorohiko "i roto i te tīwae" ki taua tokoni te mahi i tetahi tātaitanga te whakamahi i te wha ngā mahi pāngarau tuatahi. Aue ... Ki tapawha, a kahore noa nga pakiaka tapawha o enei hātepe e kore e te tīariari. A i roto i tenei take, kia rite ki te pakiaka tapawha kahore te tātaitai? I runga anō i te auraa o te putanga pakiaka tapawha - he mea e tika ana ki te tīpako i te uara hua tau kaha whakaarokore nei tapawha te whakatata te uara o te radicand. Ko te katoa! E kore e whakahaere ki te tika i te rua ranei haora, rite he reira taea ki te tātai, te whakamahi i te tikanga o te whakareatanga pai-mohiotia i roto i te "tīwae" o tetahi pakiaka tapawha. Ki te he hāneanea koe nui ki te mahi i o meneti te tokorua. Ahakoa e kore e tino matatau tātaitai kaiwhakamahi PC ranei hanga reira i roto i te kotahi pakaukau hinga - te ahunga whakamua.

Ko tino, kei te maha whakamana te pakiaka tapawha te whakamahi i te tikanga o "marau pū": tuatahi tango i te tau nei tapawha, pakeke hāngai ki te Radicals. He pai ki te "to tatou tapawha" he iti iti iho i tenei faaiteraa. Na, te whakatika i te maha o ratou ake kaha, he mahara ki, hei tauira, whakanuia e rua, a ... tapawha ano. Ki te he nui atu i te tokomaha i raro i te pakiaka ä fakatonutonu te āta te tau taketake tata ona "tauira" i raro i te pakiaka te hua. Ka rite ki a koutou e taea e kite - kahore he tātaitai, te kaha anake ki kia whakaaro "i roto i te tīwae". O te akoranga, i reira e maha hātepe pūtaiao, me te korerorero, ka papaitia kia rorohiko pakiaka tapawha, engari mo te "whakamahi kāinga" homai horomanga i runga 100% whakawhirinaki i roto i te hua.

Aue, tata wareware ahau ki te whakaū i tona reo matatini nui haere, tātai i te pakiaka tapawha o te tau i tohua i mua 12345. Hanga he taahiraa i te taahiraa:

1. Tangohia karu, X = 100. tātai matou: X * X = 10,000 pūmanawa i teitei - i te hua ko te iti iho i te 12345.

2. Whakamātauria ki karu hoki, X = 120. Na: X * X = 14400.I ano ki te raupapa pūmanawa - te hua o te neke atu i 12345.

3. Ko te whiwhi i runga "marau" o 100 me 120. Kōwhiria he tau hou - 110 me 115. whiwhi matou, aua, 12100, me te 13225 - Fork vāofi.

4. Whakamātauria ki "tupurangi" X = 111. * Haere X X = 12321. He tata nui ki te 12345. I roto i runga ki te tika e hiahiatia ana tenei tau "pai" taea tonu mutu i runga i te hua whiwhi ranei. Ko te katoa. I korero ai - Ko te tino māmā, me te kahore te tātaitai mea katoa.

he moka rawa o hītori ...

patua ratou ki runga ki te whakaaro ki te whakamahi i te pakiaka tapawha tonu Pythagoreans, ākonga kura me kau muimui o Pythagoras, 800 BC a ka "rere" mo ngā āhuatanga hou i roto i te mara o tau. Na i taua haere mai te wahi i?

1. Ko te otinga o te raruraru ki te tango i te pakiaka, homai he hua i roto i te puka o te piha haapiiraa hou o tau. i huaina ratou noatia, e ko te ki te mea, "poauau" no te mea kahore e tuhia ratou tau oti. Ko te tauira tino matarohia o tenei ahua - te pakiaka tapawha o 2. hāngai ana tēnei take ki te tātaitanga o te hauroki o te tapawhā ki te taha rite ki te 1 - e ko, te mana o te kura o Pythagoras. tahuri te reira i roto i taua he tapatoru ki te rahi rawa motuhake o te taha kotahi, te tāroa o te rahi faaite e te e te maha, i roto i nei "kahore he mutunga." Na i roto i te pāngarau puta noatia tau.

2. Kei te mohiotia te reira e tīmata hikareia raruraru. tahuri te reira i roto i taua kei tenei mahi pāngarau tetahi taea - tango i te pakiaka tapawha, e kore matou e matau ki te tapawha o te tau, pai kino ranei, ko te faaiteraa tuwhena. Tenei papû ore, te hua rua o te mahi kotahi, ka tuhia.

Ko te ako e pā ana ki tenei āwangawanga tītohunga ko te aronga i roto i te pāngarau, ka karanga te ariā o te ana'iraa matatini, i te mea faufaa mahi nui i roto i te ahupūngao pāngarau o.

Ata whakairohia, te ti'araa o te pakiaka - he - tono i roto i tona "tauhanga Universal" Ko te taua whaikörero Newton, ka kua titiro hou rite tuhi i te pakiaka kua mohiotia mai 1690 i te pukapuka te Wīwī Rolle "Guide taurangi".
