Ces, tus nqi ntawm 1 infinity yog dab tsi?
Qhov tseem ceeb, 1 divoded los ntawm tus lej loj heev tau ze rau xoom, yog li… 1 faib los ntawm tsis kawg , yog tias koj tuaj yeem ncav cuag tsis kawg , yog 0.
Ib sab saum toj no, koj yuav suav cov kev txwv li cas? Nrhiav qhov txwv los ntawm kev nrhiav tus lej qis tshaj plaws
- Nrhiav cov LCD ntawm cov seem nyob rau sab saum toj.
- Faib tus lej rau saum.
- Ntxiv lossis rho tawm cov lej thiab tom qab ntawd tshem tawm cov ntsiab lus.
- Siv cov cai rau feem ntau kom yooj yim ntxiv.
- Hloov tus nqi txwv rau hauv txoj haujlwm no thiab ua kom yooj yim.
Dhau li ntawm no, dab tsi yog lub hauv paus square ntawm infinity?
Teb thiab piav qhia: Lub square cag ntawm infinity yog tsis kawg . Yog tias koj xaiv tus lej thiab muab faib los ntawm nws tus kheej, koj yuav muaj squared tus lej.
Yuav ua li cas koj muab cov hauv paus square?
Rau multiply square cag , ua ntej ntau cov radicans, lossis cov lej hauv qab lub cim radical. Yog hais tias muaj cov coefficients nyob rau hauv pem hauv ntej ntawm lub radical kos npe, ntau lawv ua ke thiab. Thaum kawg, yog tias cov radicand tshiab tuaj yeem muab faib tawm los ntawm ib qho zoo meej square , qhia tawm qhov no zoo meej square thiab ua kom yooj yim rau nws.

Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Yuav ua li cas koj muab ntau square cag?
Txoj Kev 2 Multiplying Square Roots WithCoefficients Muab cov coefficients. Ib tug coefficient yog ib tug lej nyob rau hauv pem hauv ntej ntawm lub radical kos npe. Ntxiv cov radicans. Qhia tawm cov squares zoo meej hauv radicand, yog tias ua tau. Muab lub hauv paus square ntawm lub perfectsquare los ntawm cov coefficient
Yuav ua li cas koj daws cov zauv sib xyaw nrog proportions?
Yuav kom daws tau qhov proportions nrog cov lej sib xyaw yooj yim, tsuas yog tig tus lej sib xyaw ua ib feem tsis tsim nyog. Kho cov proportions nrog cov lej sib xyaw los ntawm kev siv tus lej sib npaug nrog kev pab los ntawm tus kws qhia lej hauv daim vis dis aus pub dawb no ntawm proportions hauv lej
Yuav ua li cas koj daws cov hauv paus plaub hau nrog lub hwj chim?
VIDEO Ib yam li ntawd, puas exponents tshem tawm cov hauv paus square? Qhov ntawd txhais tau tias yog tias koj muaj qhov sib npaug nrog cov hauv paus plaub hau hauv nws, koj tuaj yeem siv qhov "squaring", lossis exponents , tshem tawm cov hauv paus plaub hau .
Koj yuav daws qhov coefficient li cas los ntawm kev ua kom tiav cov square?
Tam sim no peb tuaj yeem daws qhov sib npaug Quadratic hauv 5 kauj ruam: Kauj Ruam 1 Faib tag nrho cov ntsiab lus los ntawm a (cov coefficient ntawm x2). Kauj Ruam 2 Txav tus lej sij hawm (c/a) mus rau sab xis ntawm kab zauv. Kauj Ruam 3 Ua kom tiav cov square ntawm sab laug ntawm qhov sib npaug thiab sib npaug qhov no los ntawm kev ntxiv tus nqi qub rau sab xis ntawm kab zauv
