Multiplying Letters hauv Algebra
- A tsab ntawv tuaj yeem yog multiplied nrog tus lej. Sau tus lej nyob rau pem hauv ntej ntawm tus tsab ntawv .
- A tsab ntawv tuaj yeem yog multiplied nrog qhov sib txawv tsab ntawv . Sau tus ntawv nyob ib sab.
- A tsab ntawv tuaj yeem yog multiplied nrog tib yam tsab ntawv . Thaum koj ntau a tsab ntawv nrog nws tus kheej, siv tus lej exponent.
Tib neeg kuj nug, koj puas tuaj yeem sib npaug zoo li cov ntsiab lus?
Multiplying Terms Rau nqe lus rau ua LIKE , lawv yuav tsum muaj tib lub hauv paus rau tib lub exponent(s). Cov coefficient tuaj yeem yog dab tsi. Koj tuaj yeem muab ntau ntxiv thiab faib tsis zoo li THIAB zoo li cov ntsiab lus.
Ib yam li ntawd, koj yuav ua li cas sib npaug zog? Tus exponent "product rule" qhia peb tias, thaum twg kev sib npaug ob hwj chim uas muaj tib lub hauv paus, koj tuaj yeem ntxiv cov exponents. Hauv qhov piv txwv no, koj tuaj yeem pom nws ua haujlwm li cas. Ntxiv cov exponents tsuas yog luv luv! Cov " zog txoj cai"hais rau peb tias yuav tsa ib tug zog rau a zog , xwb ntau cov exponents.
Xav txog qhov no, koj puas tuaj yeem muab tus lej suav nrog qhov sib txawv?
Tab sis koj tseem ua tau 'tsis muab sib txawv sib txawv . Thaum twg multiplying variables , koj ntau cov coefficients thiab sib txawv zoo li qub. Yog tias cov hauv paus yog tib yam, koj tuaj yeem muab ntau ntxiv lub hauv paus los ntawm merelyadding lawv exponent.
Lub sij hawm hloov pauv yog dab tsi?
5 sij hawm 7 = 35. Thaum ua hauj lwm nrog sib txawv , nws yog ib qho tseem ceeb kom nkag siab txog cov cim. Tom qab ntawd tus lej nyob rau hauv pem hauv ntej ntawm a sib txawv , hu ua coefficient, qhia tias muaj pes tsawg sij hawm tus sib txawv tau ntxiv rau nws tus kheej. 3 x = x + x.

Cov ntaub ntawv dab tsi ua rau cov ntawv sau npe hauv cov tshuaj formula muab?
Cov ntawv lossis cov ntawv uas sawv cev rau lub ntsiab lus hu ua nws lub cim atomic. Cov lej tshwm sim raws li cov ntawv sau npe hauv cov qauv tshuaj qhia txog tus lej ntawm atoms ntawm lub caij tam sim ua ntej subscript. Yog tias tsis muaj subscript tshwm sim, ib qho atom ntawm lub ntsiab yog tam sim no
Yuav ua li cas koj nrhiav tau daim ntawv tivthaiv ntawm ib vector muab qhov magnitude thiab lub kaum sab xis?
VIDEO Khaws qhov no hauv kev xav, puas yog 0 ib chav vector? A unit vector yog a vector uas muaj qhov loj ntawm 1. Cov ntawv sau sawv cev rau tus qauv, lossis qhov loj, ntawm vector v. Basic unit vectors yog i = (1, 0 ) thiab j = ( 0 , 1) uas yog ntev 1 thiab muaj cov lus qhia raws qhov zoo x-axis thiab y-axis feem.
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
