Rau hloov los ntawm daim ntawv exponential rau logarithmic daim ntawv , txheeb xyuas lub hauv paus ntawm lub exponential equation thiab txav lub hauv paus mus rau lwm sab ntawm lub cim sib npaug thiab ntxiv lo lus log ”. Tsis txhob txav ib yam dab tsi tab sis lub hauv paus, lwm tus lej lossis qhov sib txawv yuav tsis hloov sab.

Tsis tas li ntawd, koj yuav ua li cas los ntawm daim ntawv logarithmic mus rau daim ntawv exponential?

Yuav Ua Li Cas: Muab ib qho kev sib npaug hauv logarithmic daim ntawv logb(x)=y l o g b(x) = y, convert it to daim ntawv exponential . Tshawb xyuas cov kev sib npaug y = logbx y = l o g b x thiab txheeb xyuas b, y, thiab x. Rewrite logbx=y l o g b x = y as by=x b y = x.

Qhov thib ob, koj yuav hloov cov log hauv paus li cas? Feem ntau siv hauv paus yog obviously puag 10 thiab puag e vim lawv tib leeg xwb hauv paus uas tshwm ntawm koj lub laij lej !! Hloov ntawm puag qauv Log b x = Log ib x/ Log ib b Xaiv ib qho tshiab puag thiab cov qauv hais tias nws yog sib npaug rau cov log ntawm tus lej hauv qhov tshiab puag faib los ntawm cov log ntawm cov laus puag hauv qhov tshiab puag.

Ib yam li ntawd, daim ntawv exponential yog dab tsi rau cov cav?

Logarithmic rau Exponential Form . Yog li ntawd, a log yog ib exponent ! y = log bx yog thiab tsuas yog by = x rau tag nrho x> 0 thiab 0<b≠1. Piv txwv 1: Sau log 5125 = 3 po daim ntawv exponential.

Lub log yog dab tsi?

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.
