A radical sib npaug yog ib kev sib npaug uas ib tug variable nyob rau hauv a radical . Rau daws a radical sib npaug : cais cov radical qhia txog qhov sib txawv. Yog ntau tshaj ib radical qhia txog qhov sib txawv, ces cais ib qho ntawm lawv. Nce ob sab ntawm lub kev sib npaug mus rau qhov index ntawm cov radical.

Tsuas yog li ntawd, piv txwv radical equation yog dab tsi?

Piv txwv : daws √(2x−5) − √(x−1) = 1. cais ib lub hauv paus square:√(2x−5) = 1 + √(x−1) square ob sab: 2x−5 = (1 + √ (x-1))². Peb tau tshem tawm ib lub hauv paus square. Luas sab xis: 2x−5 = 1 + 2√(x−1) + (x−1)

Ib yam li ntawd, koj yuav daws cov kev sib npaug sib npaug li cas? Cov kauj ruam los daws qhov rational equation yog:

Nrhiav tus denominator.
Muab txhua yam los ntawm tus lej feem.
Ua kom yooj yim.
Tshawb xyuas cov lus teb kom paub tseeb tias tsis muaj kev daws teeb meem ntxiv.

Ua raws li qhov kev pom no, koj txhais li cas radical?

Hauv lej, a radical kev qhia yog txhais raws li ib qho kev qhia uas muaj a radical (√) cim. Ntau tus neeg yuam kev hu qhov no yog 'square root' cim, thiab ntau zaus nws yog siv los txiav txim lub hauv paus square ntawm tus lej. Txawm li cas los xij, nws kuj tuaj yeem siv los piav qhia txog lub hauv paus cag, lub hauv paus plaub, lossis siab dua.

Koj yuav daws tau qhov sib npaug li cas algebraically?

Kauj Ruam 1: Ntxiv ob qhov sib npaug

Kauj ruam 2: daws rau x.
Kauj Ruam 3: Txhawm rau nrhiav y-tus nqi, hloov hauv 3 rau x hauv ib qho ntawm qhov sib npaug.
Kauj ruam 4: daws rau y.
Kauj Ruam 5: Txheeb xyuas qhov kev daws teeb meem raws li tus khub xaj.
Yuav ua li cas yog tias ntxiv lossis rho tawm tsis tshem tawm qhov hloov pauv? Piv txwv. 3x – y = 8.x + 2y = 5.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?

Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules

Dab tsi yog qhov kev daws teeb meem ntawm kab?

Ib qhov system ntawm kab zauv sib npaug muaj ob lossis ntau qhov sib npaug piv txwv li. y = 0.5x + 2 y = x - 2. Cov kev daws teeb meem ntawm xws li ib qho system yog qhov kev txiav txim khub uas yog kev daws rau ob qho tib si sib npaug. Kev daws rau qhov system yuav nyob rau hauv qhov chaw uas ob kab sib tshuam

Dab tsi yog kev daws teeb meem hauv chemistry BBC Bitesize?

Ib qho kev daws teeb meem yog tsim thaum lub ntsiab lus, feem ntau yog cov khoom sib xyaw ua ke, yog yaj rau hauv cov kua hu ua hnyav, feem ntau yog dej

Dab tsi xim yog phenol liab nyob rau hauv ib qho kev daws teeb meem?

Phenol liab yog cov kua qaub-puag qhia. Nws yog tsim los ntawm condensing ob moles ntawm phenol nrog ib tug mole ntawm o-sulfobenzoic acid anhydride. Phenol Liab yog siv los ua pH qhia hauv daim ntawv thov kab lis kev cai ntawm tes. Kev daws ntawm phenol liab yuav muaj xim daj ntawm pH ntawm 6.4 lossis qis dua thiab xim liab ntawm pH
