Digiri katundu

Erection wa mphamvu zachilengedwe Nthawi yomweyo yake kubwerezabwereza imayambitsa inteja nthawi. Number, mobwerezabwereza chinthu chimodzi - Kodi maziko a digiri ndi chiwerengero kusonyeza chiwerengero cha zinthu zomwezo, wotchedwa amalimbikitsa. Chifukwa cha zochita kuphedwa ndi kukhala ndi digiri. Mwachitsanzo, atatu mwa mlingo wachisanu ndi kubwereza kwa chiwerengero atatu mu mawonekedwe a multiplier kasanu ndi kamodzi.

Foundation digiri mwina chiwerengero wina osati ziro.

Wachiwiri ndi wachitatu manambala digiri ndi mayina apadera. Ndi moyenera, apakati ndi kyubu.

Mphamvu woyamba kutenga wokha ngati angapo.

Pakuti manambala zabwino komanso kudziwa mlingo wa kukhala chizindikiro zomveka. Monga ife tonse tikudziwa, aliyense chiwerengero zomveka analembedwa nusu, ndi numerator amene ali wonsewo, chimene chachititsa - zachilengedwe, kuti ndi inteja zabwino osiyana mgwirizano.

Digiri ndi chizindikiro zomveka ndi muzu wa digiri wofanana chimene chachititsa wa amalimbikitsa, ndipo radicand - m'munsi mphamvu anakweza mphamvu wofanana numerator lapansi. Mwachitsanzo: atatu pamwamba 4/5 ya mlingo wachisanu ndi wofanana ndi zitatu mu wachinayi.

Taonani katundu akuwuka mwachindunji ku matanthauzo a ankaona:

• aliyense chiwerengero abwino digiri zomveka - zabwino;

• mtengo wa chizindikiro kwa eni sadalira pa mawonekedwe a kujambula ake;

• ngati tsinde ndi zoipa, mlingo wa manambala zomveka si kumatanthauza.

Ngati maziko abwino a katundu wa digirii kaya chandamale woona.

Katundu ndi chizindikiro chilengedwe cha mlingo:

1. Yochulutsa mlingo wa kukhala m'munsi chomwecho, m'munsi yatsala zikutsatiridwa ndi kuikidwa zizindikiro. Mwachitsanzo: ndi kuchulukitsa mlingo wachisanu atatu ndi zitatu mu chiwiri kuti akhumi digiri atatu (5 + 7 = 12).

2. Pamene tikugawana mphamvu ndi m'munsi chomwecho, iwo atsala zikutsatiridwa, ndi manambalawo proofreads. Mwachitsanzo: pamene ogaŵikana atatu atatu citatu lachisanu digiri analandira atatu lofanana mbali zonse (8-5 = 3).

3. Pamene mlingo yokhudza m'munsi yatsala zikutsatiridwa ndi zithunzi ndi kuchuluka. Mwachitsanzo: pamene akumanga 3 m'mwezi wachisanu ndi chiwiri perekani 3 makumi atatu ndi kasanu (5x7 = 35).

4. kumanga mankhwala kufika yemweyo inamangidwa chilichonse mwa zinthu. Mwachitsanzo: ntchito 2x3 kumanga mankhwala chachisanu zopezera awiri chachisanu ndi atatu wachisanu.

5. chilili nusu mu digiri ku digiri womwewo wa akuika ndi numerator ndi chimene chachititsa. Mwachitsanzo: pomanga 2/5 m'mwezi wachisanu kulandira kachigawo, ndi numerator amene - awiri wachisanu, pa chimene chachititsa wa - asanu, wachisanu.

katundu izi lotani kwa mlingo wa exponents fractional.

Katundu digiri ndi amalimbikitsa zomveka

Ife timathandiza ena matanthauzo. Wina osati 0 chiwerengero chenicheni anamuukitsa kwa ziro ndi wofanana ndi munthu.

Uliwonse kuposa 0 chiwerengero chenicheni anamuukitsa kwa mphamvu ndi inteja amalimbikitsa zoipa - nusu ndi chimene chachititsa ndi numerator a pachikhalidwe ndi, mphamvu ya nambalayi, koma ndi mbali zosiyana.

Ife yothandiza katundu wa digiri angapo latsopano limene ikukhudzana bwanji ndi exponents zomveka.

Digiri ndi chizindikiro zomveka si asintha chulutsa kapena gulu la numerator ndi chimene chachititsa wa index ake pa wosiyana ndi ziro ndi nambalayi.

M'tsinde mwa wagawo ndi:

• ngati index ndi zabwino, mlingo wa kuposa 1;
• ngati zoipa - osachepera limodzi.

M'tsinde mwa n'komwe M'malo mwake:

• ngati index ndi HIV, ndiye mlingo wa osachepera limodzi;
• ngati zoipa - amkulira 1.

Pamene amalimbikitsa ukuwonjezeka, ndiye:

• kuwonjezeka mlingo palokha, ngati tsinde ndi wamkulu kuposa wina;

• amachepetsa ngati tsinde ndi zosakwana umodzi.
