Txoj Kev 1 Simplifying ib Square Root byFactoring
- Nkag siab factoring .
- Faib los ntawm qhov tsawg tshaj plaws prime tus lej ua tau.
- Rewrite tus square cag raws li ib tug multiplication teeb meem.
- Rov ua dua nrog ib tus lej ntxiv.
- Ua kom tiav yooj yim los ntawm "rub tawm" ib tug integer.
- Muab cov lej ntau ua ke yog tias muaj ntau tshaj ib.
Kuj nug, kuv yuav ua li cas yooj yim radicals?
Yuav Ua Li Cas Yooj Yim Radicals Cov kauj ruam
- Nrhiav qhov loj tshaj plaws zoo meej square uas yog qhov tseem ceeb ntawm theradicand.
- Rewrite the radical as a product of the square root of 4 (foundin the last step) thiab nws qhov zoo sib xws (2)
- Ua kom yooj yim.
- Nrhiav qhov loj tshaj plaws zoo meej square uas yog qhov tseem ceeb ntawm theradicand (ib yam li ua ntej)
Tsis tas li ntawd, tus nqi ntawm square root yog dab tsi? Square, Lub voos xwmfab, Square hauv paus thiab Cubic hauv paus rau cov lej suav nrog 0-100
| Number x | Square x2 | Square Root x1/2 |
|---|---|---|
| 2 | 4 | 1.414 |
| 3 | 9 | 1.732 |
| 4 | 16 | 2.000 |
| 5 | 25 | 2.236 |
Hauv qhov no, cov hauv paus square ntawm 18 puas tuaj yeem yooj yim?
Tus lej 18 ua ntej ntawm tag nrho cov tsis yog ib square tus lej, txhais tau tias koj tsis tuaj yeem tau txais 18 los ntawm squaring txhua tus lej. Qhov ntawd txhais tau tias yog square cag kuj tsis yog tus lej. Yog li txoj kev yooj yim tshaj plaws thiab yooj yim tshaj plaws ntawm kev nthuav tawm square root 18 ua 3√2.
Yuav ua li cas koj daws ib qho kev sib npaug los ntawm factoring?
- Txav tag nrho cov ntsiab lus mus rau ib sab ntawm qhov sib npaug, feem ntau yog sab laug, siv qhov sib ntxiv lossis rho tawm.
- Muab qhov sib npaug tag nrho.
- Teem txhua yam sib npaug rau xoom, thiab daws.
- Sau txhua qhov kev daws teeb meem los ntawm Kauj Ruam 3 raws li kev daws teeb meem rau qhov qub.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Koj puas tuaj yeem muab lub voos xwmfab hauv paus los ntawm lub hauv paus square?
Cov Khoom Muag tau nce mus rau Txoj Cai Fais Fab yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los faib cov lus qhia radical. Nco ntsoov tias cov hauv paus hniav zoo ib yam - koj tuaj yeem muab cov hauv paus plaub hau nrog cov hauv paus plaub hau, lossis cov hauv paus hniav nrog lub voos xwmfab, piv txwv li. Tab sis koj tsis tuaj yeem muab lub hauv paus square thiab lub voos xwmfab hauv paus siv txoj cai no
Lub hauv paus ntsiab lus Aufbau ua haujlwm li cas uas txhais tau hais tias orbitals tau sau los ntawm hauv qab los yog saum toj saud nyob ntawm daim duab)?
Los ntawm Hauv qab Up: Cov chav yuav tsum tau sau los ntawm hauv av pem teb mus rau. Hauv pem teb siab dua qhov kev txiav txim yuav hloov me ntsis. Aufbau Txoj Cai: cov electrons sau cov orbitals ntawm lub zog qis tshaj mus rau lub zog siab tshaj. Nyob rau hauv lub xeev av tag nrho cov electrons nyob rau hauv qis tshaj tau lub zog theem
Vim li cas koj thiaj li yuav tsum tau siv lub hauv paus ntsiab lus los saib cov Substages ntawm mitosis?
Cov lus qhia hauv paus dos feem ntau siv los kawm txog mitosis. Lawv yog cov chaw ntawm kev loj hlob sai, yog li cov hlwb tau faib sai
