M'mene tingamangire angapo mlingo zoipa - zitsanzo polongosola mu kupambana

Kusukulu ife tonse tikudziwa ulamuliro za exponentiation: chiwerengero ndi amalimbikitsa N chifukwa cha kuchulukana nambala iyi palokha N-Nowa kangapo. M'mawu ena, mphamvu ya 3 7 - 7 kuchulukitsa ndi katatu, i.e. 343. ulamuliro winanso - yomanga ndi phindu lililonse kwa unit mphamvu amapereka 0, ndi kumanga mtengo zoipa chifukwa cha exponentiation ochiritsira ngati ngakhale, ndi chifukwa chomwecho ndi "opanda" chizindikiro, ngati ali wosamvetseka.

Malamulo kupereka yankho monga kumanga chiwerengero cha mphamvu negative. Kuti tichite zimenezi, muyenera kumanga ochiritsira unsembe anakhumba kufunika kwa index gawo, kenako kugawa chifukwa unit.

Malamulo awa zimaonekeratu kuti ntchitoyo ntchito kwenikweni kugwira lalikulu zedi inafunika kupezeka njira luso. Buku ndidzachulukitsa yekha osiyanasiyana pazipita manambala mpaka makumi awiri kapena makumi atatu, ndi kuti si zoposa zitatu kapena kanayi. Izi osanenapo chakuti munthu ndiyeno wina, gawani chifukwa. Choncho, anthu amene alibe pa dzanja wapadera Chiwerengero sayansi, ife tikuonetserani inu m'mene tingamangire angapo digiri zoipa mu kupambana.

Yothetsera mavuto mu kupambana

Pamavuto ndi kumanga chilolezo mu digiri kupambana limakupatsani ntchito umodzi wa yachiwiriyo.

The choyamba - kugwiritsa ntchito chilinganizo ndi muyezo chizindikiro "kapu." Lowani mfundo izi mu fomu ndi:

Mu njira yomweyo munthu angathe kukhala ndi mtengo wolakalakika digiri iliyonse - zoipa, fractional. Timatsatira njira pansipa ndi kuyankha funso mmene kulera nambala kuti mphamvu negative. Mwachitsanzo:

Inu mukhoza kucheza ndi lolondola chilinganizo = B2 ^ -C2.

Yachiwiri - kugwiritsa ntchito okonzeka zopangidwa "digiri", kulandira mkangano awiri kuvomerezedwa - chiwerengero ndi mlingo. Kuyamba ntchito, ndi okwanira mu aliyense kwaulere selo cholembedwa "ofanana" (=), kusonyeza chiyambi cha chilinganizo, ndipo kulowa mawu pamwambapa. Mpaka kusankha maselo awiri, omwe mukugwira nawo ntchito (kapena mwachindunji nambala yeniyeni pamanja), ndipo dinani Enter. Tiyeni tione zitsanzo yosavuta.

Monga mukuonera, palibe zovuta m'mene angamangirirane chiwerengero cha mphamvu zoipa, ndipo amangoona ntchito kupambana. Ndipotu, chifukwa ntchito imeneyi angagwiritsidwe ntchito mwachizolowezi pa chizindikiro "kapu" ndi yabwino kusunga anamanga-mu dongosolo. Izi yodziŵika kuphatikiza!

Sunthani pa zitsanzo zina. Kumbukirani ulamuliro omangira manambala mu mphamvu zoipa chikhalidwe fractional, ndi kuwona kuti vutoli zosavuta kuti kuwathetsa kupambana.

exponents fractional

Mwa chidule, aligorivimu kwa kuwerengetsa chiwerengero cha fractional index lotsatira.

1. Sinthani mbali fractional mu zonse kapena osasamba nusu.
2. Kumanga manambala wathu mu numerator wa kachigawo analandira losandulizika.
3. Chochokera kwa manambala yapitayi ndime kuwerengera mizu ndi proviso kuti index wa muzu ndi chimene chachititsa wa kachigawo zopezera sitepe yoyamba.

Inu mungavomereze kuti ngakhale pamene ntchito mwa manambala ang'ono ndi tuzigawo twa yoyenera kuwerengetsera amenewa zingatenge nthawi yaitali. Chabwino, kupambana spreadsheet zilibe kanthu angati nanga digiri chilili. Yesani kuganiziratu pa kupambana fomu chitsanzo zotsatirazi:

Pogwiritsa ntchito malamulo pamwamba, mukhoza kuchongetsa ndi kuonetsetsa kuti mawerengedwe wapangidwa molondola.

Kumapeto kwa nkhaniyi ife kupereka mu mawonekedwe a matebulo ndi mitunduyi ndi zotsatira za zitsanzo zingapo za mmene kumanga chiwerengero cha mphamvu zoipa, komanso zitsanzo zochepa kugwira ndi manambala fractional ndi madigiri.

zitsanzo tebulo

Yang'anani ndi kupambana lolembamo The zitsanzo fomu. Kupanga zinthu ntchito bwino, muyenera kugwiritsa ntchito ulalo wosanganiza pamene kukopera njira. Angagwirizanitse ndime chiwerengero munali chiwerengero anamangapo ndi mzere nambala munali chigawo chimodzi. chilinganizo wanu Chioneke mawonekedwe zotsatirazi :. «= $ B4 ^ C $ 3"

Onani kuti manambala zabwino (ngakhale sanali inteja) ndi mavuto n'komwe masamu zizindikiro. Palibe mavuto ndi erection a manambala aliyense mu ntchito yonse. Koma ntchito yomanga chiwerengero zoipa ndi mphamvu fractional mu sitolo kwa inu cholakwa, chifukwa n'zosatheka kumvera malamulo mwachindunji pachiyambi m'nkhani za ntchito yomanga manambala zoipa, chifukwa parity - ndi khalidwe chabe la inteja ndi.
