Tsuas yog cov coefficients zoo li nqe lus txawv. Txij li thaum ntxiv los yog rho tawm tsis zoo li cov ntsiab lus zoo li sib tov txiv apples thiab txiv kab ntxwv - tsuas yog nyiam cov ntsiab lus tuaj yeem ua ke. Rau ua ke zoo li nqe lus , ntxiv cov coefficients thiab muab cov lej sib npaug los ntawm qhov sib txawv.
Xav txog qhov no, koj tuaj yeem sib npaug tsis zoo li cov ntsiab lus?
Tsis zoo li Cov Cai yog tej nqe lus uas tsis muaj tib lub hauv paus rau tib tus exponent(s). Koj tuaj yeem muab ntau ntxiv thiab faib tsis zoo li THIAB nyiam nqe lus.
Koj ua li cas yooj yim tsis zoo li cov lus? Nov yog cov kauj ruam yooj yim los ua kom yooj yim rau kev qhia algebraic:
- tshem cov kab lus los ntawm kev sib npaug.
- siv cov kev cai exponent kom tshem tawm cov kab lus nyob rau hauv cov nqe lus nrog exponents.
- ua ke zoo li cov ntsiab lus los ntawm kev ntxiv cov coefficients.
- muab cov tsis tu ncua.
Dhau li ntawm no, cov ntsiab lus zoo li lossis tsis zoo?
" Zoo li Cov Cai " yog cov Terms Leej twg Variables thiab Exponents zoo ib yam. " Tsis zoo li Cov Cai " yog cov Terms Leej twg Variables thiab Exponents yog tib yam.
Dab tsi zoo li thiab tsis zoo li feem?
Zoo li thiab Tsis Zoo Li Fractions . Cov ib feem nrog tib lub denominators raug hu zoo li feem ntau . Hauv pab pawg (ii) tus denominator ntawm txhua tus feem yog txawv, i.e., tus denominators ntawm tag nrho cov ib feem txawv. Cov ib feem nrog sib txawv denominators raug hu tsis zoo li feem ntau.

Koj puas tuaj yeem ntxiv Tsis zoo li radicals?
Tab sis tej zaum koj yuav tsis tuaj yeem ua kom yooj yim qhov sib ntxiv tag nrho mus rau ib tus lej. Ib yam li 'koj tsis tuaj yeem ntxiv txiv apples thiab txiv kab ntxwv', yog li koj kuj tsis tuaj yeem ua ke 'tsis zoo li' cov ntsiab lus radical. Txhawm rau kom muaj peev xwm sib txuas cov ntsiab lus radical ua ke, cov ntsiab lus yuav tsum muaj tib yam radical
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Txoj cai thermodynamic twg hais tias koj Tsis tuaj yeem hloov 100 feem pua ntawm cov cua sov rau hauv cov khoom siv hluav taws xob ntawm cov lus teb xaiv?
Txoj Cai thib ob
Koj tuaj yeem ntxiv cov kab mob zoo rau hauv av li cas?
Pub rau lawv. Microbes noj thiab zom cov organic. Khaws ntxiv compost, manure, cog cuttings, ntoo nti mulch thiab lwm yam, rau koj cov av. Tsuas yog cov nroj tsuag loj hlob hauv av yuav muab cov organic teeb meem rau microbes noj
