Ntawm no yog cov cai. Thaum ntxiv lossis rho tawm cov lej hauv kev tshawb fawb, tus lej yuav tsum yog tib yam. Cov exponents yog tib yam, yog li ntxiv cov coefficients. Thaum ntxiv lossis rho tawm cov lej hauv kev tshawb fawb, cov lej yuav tsum yog tib yam.
Thaum ntxiv cov lej hauv cov ntawv tshawb fawb koj yuav tsum?
Yuav tsum tau ntxiv lossis rho tawm, ob tus lej hauv kev tshawb fawb yuav tsum tau tswj kom lawv lub hauv paus muaj qhov sib npaug-qhov no yuav ua kom cov lej sib raug hauv lawv cov coefficients muaj tib qhov chaw tus nqi.
Yuav ua li cas cov cai uas koj yuav tsum ua raws thaum ntxiv thiab rho tawm tag nrho cov uas siv?
Cov cai dab tsi koj yuav tsum ua raws thaum ntxiv thiab rho tawm? Tshawb xyuas txhua yam uas siv tau. Tus lej yuav tsum yog tib yam yog li cov lej ua ntej tuaj yeem muab ntxiv lossis rho tawm. Qhov tshwm sim muaj tib tus lej lej lej raws li tus lej tsawg kawg nkaus.
Yuav ua li cas thiaj yog 60220000000000000000000000000000000000000000000000000
Piv txwv li, coj tus lej 602, 200, 000, 000, 000, 000, 000, 000. Siv cov ntawv sau tshawb fawb, tus lej no tuaj yeem qhia tau tias 6.022x10 2 3, uas yog qhov yooj yim dua. Ntau, ntau tus lej hauv chemistry, physics, thiab lwm yam kev tshawb fawb yuav tshwm sim hauv daim ntawv scientific notation.
Koj ntxiv thiab muab ntau npaum li cas?
Yuav kom muab ob tus lej hauv kev tshawb fawb, muab lawv cov coefficients thiabntxiv lawv cov exponents. Txhawm rau faib ob tus lej hauv kev tshawb fawb, faib lawv cov coefficients thiab rho tawm lawv cov lej.
