Izakhiwo degree

Ukwakhiwa kwezindlu amandla yemvelo yayo ngokushesha ukuphindaphinda into e inamba izikhathi. Inombolo, okuphindaphindiwe njengesici esibangela i - kuyisisekelo ngezinga futhi nenombolo kukhombisa isibalo lezi zici, ebizwa ngokuthi okungekho. Umphumela yezenzo ababulawa futhi ngezinga elithile. Ngokwesibonelo, amathathu neziqhelile kuyinto kwesibalo amathathu ngendlela Okuphindaphinda izikhathi eziyisithupha.

Foundation degree kungenzeka yimuphi omunye kunoziro inombolo.

Eyesibili neyesithathu izinombolo degree zinamagama ekhethekile. Kuyinto, ngokufanele, isikwele kanye cube.

Ngo amandla wokuqala ukuthatha ngokwaso njengoba inombolo.

Ukuze izinombolo omuhle futhi ukucacisa degree kokuba inkomba okunengqondo. Njengoba sazi sonke, noma iyiphi inombolo okunengqondo ebhaliwe njengendlela ingxenyenamba, le numerator okuyinto wonke, i-zihilela - the esingokwemvelo, okusho inombolo ephelele engaphezulu kweqanda sihluke ubunye.

Degree nge inkomba okunengqondo luyimpande yazo degree elilingana zihilela we eksponenti, futhi radicand - isisekelo samandla ephakanyiswe emandleni ilingane numerator. Ngokwesibonelo: ezintathu enhlokweni phezulu 4/5 of the degree yesihlanu ilingana amathathu lesine.

Phawula ezinye izakhiwo ezivele ngenxa ngokuqondile izincazelo kubhekwe:

• noma iyiphi inombolo okuhle degree okunengqondo - omuhle;

• ukubaluleka inkomba nokuphathwa akuxhomekile ukuma ukuqoshwa yayo;

• uma base alivumi, degree of izinombolo okunengqondo kungukuthi echaziwe.

Uma isisekelo esihle ka izakhiwo degree kungakhathaliseki ilitshe kweqiniso.

Izakhiwo nge inkomba engokwemvelo ngezinga:

1. Ukuphindaphinda degree kokuba base esifanayo, base ishiywa izinkomba ingashintshiwe futhi ibekwe. Ngokwesibonelo: ngokuvele azalane ngezinga yesihlanu ezintathu ezintathu eyesikhombisa yeshumi nambili athola khona iziqu zobudokotela ezintathu (5 + 7 = 12).

2. Lapho sokuhlukanisa amandla sizindza esifanayo, washiya azizange zishintshe, futhi izibalo Kulungisa emaphutsa. Ngokwesibonelo: uma ihlukaniswe ezintathu emithathu eyesishiyagalombili yesihlanu-degree etholwe ezintathu yisikwele (8-5 = 3).

3. Uma ezingeni ophakamayo, base ishiywa azizange zishintshe, futhi izibalo ziziningi. Ngokwesibonelo: uma ekwakheni 3 eyesihlanu Sinike lwesikhombisa 3 wamashumi amathathu nanhlanu (5x7 = 35).

4. Ukwakha umkhiqizo ngokwezinga okufanayo is esakhiwe ngamunye izici. Ngokwesibonelo: umsebenzi wokwakha 2x3 e umkhiqizo yesihlanu etholwe lesihlanu emibili kuya kwemithathu lesihlanu.

5. Ukuze sokuzakhela ingxenyenamba e Izinga ngezinga elifanayo ukwakha le numerator kanye Iningi. Ngokwesibonelo: ekwakhiweni 2/5 lesihlanu wamukela ingxenyenamba, le numerator zazo - amabili e-yesihlanu, zifana - amahlanu ngenyanga yesihlanu.

Lezi izindawo bamba degree of exponents wamaqhuzu.

Izakhiwo degree ne exponent okunengqondo

Thina ukwethula ezinye izincazelo. Noma yimuphi omunye kuka 0 inombolo engokoqobo ephakanyiswe zero ilingana komunye.

Noma yimuphi kuka 0 inombolo engokoqobo ephakanyiswe emandleni nge negative inamba exponent - ingxenyenamba nge zifana futhi numerator unit, amandla inani elifanayo, kodwa kokuba ingxenye okuphambene.

Thina ukwelekelela izakhiwo degree eziningana ezintsha, ezihlobene exponents okunengqondo.

Degree nge inkomba okunengqondo engashintshwa ku ukubuyabuyelela noma division of the numerator kanye Iningi Inkomba kwayo ukungalingani zero inombolo efanayo.

Ngaphansi kwesithombe senqaba iyunithi:

• uma Inkomba omuhle, ezingeni kuka 1;
• uma omubi - engaphansi.

Ngaphansi kwesithombe senqaba engaphansi, kunalokho:

• uma Inkomba omuhle ke degree of engaphansi;
• uma omubi - mkhulu kunezinhliziyo 1.

Lapho ukwanda exponent bese:

• okwandisa degree ngokwayo, uma isizinda mkhulu kwelilodwa;

• incipha uma base lingaphansi kunobunye.
