Q thiab S tsis sib npaug 0
- Kauj ruam 1: Factor ob tus lej thiab tus lej.
- Kauj ruam 2: Sau ua ib qho feem .
- Kauj ruam 3: Simplify lub rational qhia .
- Kauj ruam 4: Ntau txhua yam tseem ceeb hauv tus lej thiab / lossis tus lej.
- Kauj ruam 1: Factor ob tus lej thiab tus lej.
- Kauj ruam 2: Sau ua ib qho feem .
Tom qab ntawd, koj yuav muab ntau npaum li cas los yog faib cov lus qhia txog kev xav?
Rau multiply rational expressions , thawj qhov tseem ceeb txhua tus lej thiab tus lej thiab tshem tawm txhua yam uas koj tuaj yeem ua tau. Ces ntau koj tshuav dab tsi. Rau faib , tsuas yog tig lub divisor (lub sij hawm koj nyob kev faib los ntawm) thiab tom qab ntawd ntau . Hauv lej-hais lus, hu ua kev sib npaug los ntawm kev sib raug zoo ntawm tus divisor.
Tsis tas li ntawd, ntau npaum li cas hauv algebra? Thaum peb ntau powers, peb ntxiv cov exponents. Piv txwv li, xav tias peb ntau (3x) (4x squared). Zoo, ua ntej ntawm tag nrho cov, peb yuav mus ntau cov coefficients. Peb zaug plaub yog 12 thiab x x x squared, yog x cubed. Peb mam li ntxiv cov coefficient no qhov twg ntawm cov exponents ntawm y, tus 2 thiab 3 thiab peb yuav tau y mus rau 5th.
Tom qab ntawd, cov cai ntawm algebra yog dab tsi?
Cov cai yooj yim thiab cov cuab yeej ntawm Algebra
- Commutative Property of Ntxiv.
- Commutative Property of Multiplication.
- Associative Property of Ntxiv.
- Associative Property of Multiplication.
- Distributive Properties of Addition Over Multiplication.
- Qhov sib npaug ntawm tus lej tsis yog xoom tiag yog 1 / a.
- Lub additive inverse ntawm a yog -a.
- Lub additive yog 0.
Dab tsi yog qhov khoom ntawm kev nthuav qhia?
Cia peb tawg lo lus “tus khoom ntawm tus lej thiab tus lej kom nkag siab lub ntsiab lus ntawm qhov no kev qhia . Lo lus khoom txhais tau hais tias cov txiaj ntsig ntawm kev muab ob lossis ntau tus lej. Lo lus sum txhais tau tias cov txiaj ntsig ntawm kev ntxiv ob lossis ntau tus lej. Cov khoom ntawm tus lej thiab tus lej yog qhov sib xyaw ua ke ntawm cov haujlwm no.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
Dab tsi yog kev txwv nyob rau hauv ib qho kev qhia rational?
Qhov kev txwv yog tias tus denominator tsis tuaj yeem sib npaug rau xoom. Yog li hauv qhov teeb meem no, txij li 4x yog nyob rau hauv tus lej nws tsis tuaj yeem sib npaug zero. Txhawm rau nrhiav cov kev txwv ntawm kev ua kom muaj nuj nqis, nrhiav qhov tseem ceeb ntawm qhov sib txawv uas ua rau tus lej sib npaug 0
