A logarithmic kev qhia yog ib kev qhia muaj logarithms hauv nws. Rau condense logarithmic expressions txhais tau tias siv lub logarithm kev cai kom txo cov lus qhia logarithm los ntawm daim ntawv nthuav mus rau ib daim ntawv condensed. Kev paub txog cov logarithm kev cai lij choj / khoom vaj khoom tsev yuav yog qhov tseem ceeb hauv kev sib txuas lus cov lus qhia logarithm.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog cov cuab yeej ntawm lub cav?
Logarithm ntawm ib yam khoom Nco ntsoov tias lub khoom ntawm exponents thiab logarithms zoo sib xws heev. Nrog exponents, kom muab ob tug lej nrog tib lub hauv paus, koj ntxiv cov exponents. Nrog logarithms , lub logarithm ntawm cov khoom yog qhov sib npaug ntawm cov logarithms.
Ib sab saum toj no, koj yuav ua li cas daws cov kab zauv exponential? Rau daws ib exponential equation , nqa lub cav ntawm ob sab, thiab daws rau qhov sib txawv. Ln(80) yog cov lus teb tseeb thiab x=4.38202663467 yog cov lus teb kwv yees vim tias peb tau ntsuas tus nqi ntawm Ln(80).. Kos: Tshawb xyuas koj cov lus teb hauv thawj. kev sib npaug.
Dhau li ntawm no, LN sib npaug li cas?
Cov ntuj logarithm ntawm tus lej yog nws lub logarithm rau lub hauv paus ntawm kev ua lej tsis tu ncua e, qhov twg e yog tus lej tsis txaus ntseeg thiab tus lej sib npaug kwv yees li 2.718281828459. Cov ntuj logarithm ntawm x feem ntau yog sau li ln x ua , loge x, lossis qee zaum, yog tias lub hauv paus e yog implicit, tsuas yog log x.
Log2 txhais li cas?
log2(x) sawv cev rau lub logarithm ntawm x mus rau lub hauv paus 2. Mathematically, log2(x) yog sib npaug rau log (2 , x). Saib piv txwv 1. Lub logarithm rau lub hauv paus 2 yog txhais rau txhua qhov kev sib cav sib ceg x ≠ 0. log2(x) rov sau logarithms rau hauv paus 2 raws li lub ntuj logarithm: log2(x) = ln(x)/ln(2)

Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi nthwv dej zoo li cov cuab yeej ntawm lub teeb ua rau nws hloov kev taw qhia thaum nws txav ntawm ib nrab mus rau lwm qhov?
Refraction
Yuav ua li cas nrog ib tug slash los ntawm nws txhais li cas?
Thaum koj pom ib txoj kab slanted (tseem hu ua aslash) los ntawm ib lub cim, tus slash cancelsor negates lub cim. Piv txwv li, thaum peb pom cov cim no: (imagesource: geekalerts.com) peb paub tias dab tsis raug tso cai. Yog li, thaum peb pom ib kab los ntawm kev sib npaug, peb paub tias nws txhais tau tias TSIS sib npaug
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
