Yog tias tsis yog ob qho ntawm cov lus qhia saum toj no ua haujlwm thiab koj muaj lub ntsiab lus tsuas muaj ib qho exponent , koj tuaj yeem siv txoj hauv kev zoo tshaj plaws rau "tau txais caij ntawm "cov exponent : cais cov exponent lub sij hawm ntawm ib sab ntawm qhov sib npaug, thiab tom qab ntawd siv qhov tsim nyog radical rau ob sab ntawm kab zauv. Xav txog qhov piv txwv ntawm z3 - 25 = 2.
Raws li txoj cai, koj yuav tshem tawm lub zog hauv kev sib npaug li cas?
Txhawm rau daws nws koj tsuas yog siv peb lub hauv paus ntsiab lus: Tosolve an kev sib npaug xyuas seb dab tsi thab koj thiab tom qab ntawd ua tib yam ntawm ob sab ntawm lub kev sib npaug kom tau caij ntawm nws. Kom tau caij ntawm ib tug radical koj coj nws mus rau ib zog uas yuav hloov lub rational exponent rau ib tug naturalnumber.
Koj yuav ua li cas thiaj daws tau cov txiaj ntsig exponential? Rau daws ib exponential equation , coj thelog ntawm ob sab, thiab daws rau qhov sib txawv. Piv txwv 1: daws rau x v kev sib npaug . Ln(80) is the exact answer and x=4.38202663467 is a approximate answer because we haverounded the value of Ln(80).. Kos: Tshawb xyuas koj cov lus teb hauv keeb kwm kev sib npaug.
Tsis tas li ntawd, dab tsi yog qhov opposite ntawm tus exponent?
Lub logarithm yog qhov rov qab ntawm ib lub zog. Hauv lwm lo lus, yog tias peb coj lub logarithm ntawm tus lej, peb tshem tawm ib qho kev nthuav qhia.
Koj yuav daws qhov kev sib npaug ntawm algebraic li cas?
Cov kauj ruam
- Sau qhov teeb meem.
- Txiav txim siab seb yuav siv qhov sib ntxiv lossis rho tawm kom cais cov ntsiab lus sib txawv.
- Ntxiv lossis rho qhov tas li ntawm ob sab ntawm qhov sib npaug.
- Tshem tawm cov coefficient ntawm qhov sib txawv los ntawm kev faib lossis sib faib.
- daws rau qhov sib txawv.
