Exponential equations uas cov tsis paub tshwm sim ib zaug
Qhov tshwm sim yog tias tus exponential sawv ib leeg ntawm ib sab ntawm qhov sib npaug, uas tam sim no muaj daim ntawv b f = a, qhov twg exponent f muaj cov tsis paub x. Yog hais tias lub hauv paus ntawm tus exponential yog e ces coj natural logarithms ntawm ob sab ntawm kab zauv.
Ntxiv mus, dab tsi yog qhov ploj lawm exponent?
Exponent txhais tau tias pes tsawg zaus nws lub hauv paus yog siv asa yam. Kauj ruam 1: Nrhiav tus nqi ntawm tsis muaj tus exponent , peb yuav tsum faib tus lej uas nyob rau lwm sab ntawm qhov sib npaug (uas tsis muaj hwj chim) raws li ntau yam ntawm lub hauv paus ntawm tsis muaj tus exponent.
exponential equation yog dab tsi? Ib exponential equation yog ib qho uas avariable tshwm sim nyob rau hauv lub exponent , npr,. Thaum ob lub qhov muag kev sib npaug muaj tib lub hauv paus, cov exponents ib sab yog sib npaug ntawm cov cuab yeej yog, ces.
Ntawm no, koj yuav xam cov exponents li cas?
Lub hauv paus B sawv cev rau tus lej koj muab thiab tus lej exponent "x" qhia koj pes tsawg zaus koj muab lub hauv paus, thiab koj sau nws li "B^x." Piv txwv li, 8^3 yog 8X8X8 = 512 qhov "8" yog lub hauv paus, "3" yog qhov exponent thiab tag nrho cov lus qhia yog lub hwj chim.
Yuav ua li cas kom daws tau qhov integer exponent?
Saib xyuas, integer exponents yog exponents uas yog tus lej . Positive integer exponent qhia pes tsawg zaus peb yuav tsum muab lub hauv paus los ntawm nws tus kheej. Negative integer exponents qhia rau peb ua ntej tig cesumerator thiab denominator thiab mam li muab tus lej ntawd los ntawm nws tus kheej tus lej ntawm lub sijhawm.
