Tab sis koj tej zaum yuav tsis tuaj yeem ua kom yooj yim ntxiv rau txhua txoj hauv kev ib tus lej. Ib yam li " koj ua tau 't ntxiv txiv apples thiab txiv kab ntxwv", thiab koj tsis tuaj yeem ua ke " tsis zoo li " radical nqe lus. Yuav kom muaj peev xwm ua ke radical cov ntsiab lus ua ke, cov ntsiab lus yuav tsum muaj tib yam radical ib feem.
Ua li no, thaum twg koj tuaj yeem sib xyaw cov radicals?
Koj ua tau tsuas ntxiv los yog tshem tawm cov radicals ua ke yog lawv zoo li radicals . Koj add lub rho tawm lawv tib yam li ntawd koj ua zoo li cov lus qhia hauv Tutorial 25: Polynomials thiab Polynomial Functions. Ua ke cov naj npawb uas nyob pem hauv ntej ntawm cov zoo li radicals thiab sau tus lej ntawd ua ntej ntawm qhov zoo li radical ib feem.
Dab tsi yog qhov yooj yim radical? Peb hais tias SQUARE ROOT RADICAL yog yooj yim , los yog hauv nws daim ntawv yooj yim tshaj plaws, thaum lub radicand tsis muaj xwm txheej square. A radical Nws kuj tseem nyob hauv daim ntawv yooj yim tshaj plaws thaum lub radicand tsis yog ib feem. Lub radicand tsis muaj cov xwm txheej square lawm.
Tom qab ntawd, txoj cai radical yog dab tsi?
Qhov no txoj cai hais tias cov khoom ntawm ob los yog ntau tshaj tus lej tsa rau lub hwj chim yog sib npaug rau cov khoom ntawm txhua tus lej tsa rau tib lub zog. Qhov no yuav tsum yog ib lub tswv yim paub. Koj tau siv qhov no txoj cai thaum nthuav cov kab lus xws li (ab)x rau ax • bx; tam sim no koj yuav hloov nws kom suav nrog radicals ib yam nkaus.
Yuav ua li cas koj ntaus ib square root?
Yuav ua li cas thiaj ua tau ib lub cim Square hauv cov ntawv nyeem hauv koj lub computer:
- Luam thiab muab cov cim square hauv paus rau hauv koj daim ntawv: √
- Yog tias koj cov keyboard muaj tus lej ncoo, tuav lub pob [Alt] thiab ntaus 251.

Koj puas tuaj yeem siv kev txhaum thiab cos ntawm cov duab peb sab tsis zoo?
Xav txog lwm daim duab peb sab uas tsis yog txoj cai, sau npe raws li qhia nrog sab ntev x thiab y. Peb tuaj yeem muab tau ib txoj cai muaj txiaj ntsig uas tsuas muaj cov haujlwm cosine xwb. Txoj cai ntawm cosines tuaj yeem siv los nrhiav kev ntsuas ntawm lub kaum sab xis lossis ib sab ntawm daim duab peb sab uas tsis yog txoj cai yog peb paub: peb sab thiab tsis muaj kaum
Puas yog qhov tsis zoo thiab qhov zoo nqes hav tuaj yeem sib npaug?
Theorem 104: Yog hais tias ob kab muaj tib txoj kab nqes, ces cov kab yog nonverttical parallel kab. Yog hais tias ob kab yog perpendicular thiab tsis yog ib tug ntsug, ces ib tug ntawm cov kab muaj ib tug zoo nqes hav, thiab lwm yam muaj ib tug tsis zoo nqes hav. Tsis tas li ntawd, qhov tseem ceeb ntawm lawv txoj kab nqes yog qhov sib txuam
Koj tuaj yeem ntxiv cov ntsiab lus tsis zoo li cas?
Tsuas yog cov coefficients zoo li cov ntsiab lus sib txawv. Txij li thaum ntxiv lossis rho tawm tsis zoo li cov ntsiab lus zoo li sib xyaw txiv apples thiab txiv kab ntxwv - tsuas yog cov ntsiab lus zoo li tuaj yeem ua ke. Txhawm rau muab cov ntsiab lus zoo li, ntxiv cov coefficients thiab muab cov lej sib npaug los ntawm qhov sib txawv
Koj puas tuaj yeem muab cov radicals sib txawv nrog cov lej sib txawv?
Cov khoom yog ib tug zoo meej square txij li thaum 16 = 4 · 4 = 42, uas txhais tau hais tias lub square cag ntawm 16 yuav muaj tag nrho cov lus teb. Koj tsuas tuaj yeem muab ntau tus lej uas yog ob sab hauv lossis ob qho tib si sab nraud ntawm lub cim theradical. Thaum muab ntau tus lej hauv thiab tus lej sab nraud ntawm cov radical, tsuas yog muab tso rau ntawm ib sab
Koj puas tuaj yeem tsav nrog tus nres nres tsis zoo?
Yog hais tias koj muaj ib tug daig caliper, lub nres nres yuav tsis kiag li disengage los ntawm tus nto ntawm tus nres rotor. Qhov no txhais tau tias koj yuav tsav tsheb nrog cov brakes siv me ntsis txhua lub sijhawm. Kev tsav tsheb nrog lub caliper daig tuaj yeem tsim kev ntxhov siab ntawm kev sib kis, ua rau nws ua tsis tau ua ntej
