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:

1. Nrhiav tus denominator.
2. Muab txhua yam los ntawm tus lej feem.
3. Ua kom yooj yim.
4. 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

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