Txhawm rau tsim qhov muaj nuj nqi exponential, peb cia tus hloov pauv ywj pheej yog tus lej. Ib qho piv txwv yooj yim yog qhov ua haujlwm f(x)=2x … Nyob rau hauv qhov exponential lwj ntawm g(x), qhov ua haujlwm yuav txo qis hauv ib nrab txhua zaus koj ntxiv ib qho rau nws cov tswv yim x.

Yuav ua li cas koj daws tus lej exponential?

Thaum tsa lub zog rau lub zog hauv qhov kev nthuav qhia, koj pom lub zog tshiab los ntawm kev muab ob lub zog ua ke Piv txwv li, hauv kab lus hauv qab no, x rau lub zog ntawm 3 yog raug tsa mus rau lub hwj chim ntawm 6, ces koj yuav muab 3 thiab 6 mus nrhiav tau lub zog tshiab.

Puas exponential zoo ib yam li exponent?

Summary of Power vs Exponent

Ib tus exponent yog nothing tab sis tus lej lossis qhov sib txawv uas sawv cev rau tus lej ntawm lub sijhawm tus lej hauv paus tau muab faib los ntawm nws tus kheej. Hauv kev qhia lej 2^{4, 2 yog tus lej hauv paus nrog tus lej ntawm 4 lub ntsiab lus 4 yog tus lej ntawm 2 thiab daim ntawv hu ua exponential form.}

Xov xwm exponential yog dab tsi?

Peb tuaj yeem nce exponential rau lwm lub zog, lossis siv lub zog ntawm lub zog. Qhov tshwm sim yog ib tug exponential qhov twg lub hwj chim yog cov khoom ntawm tus thawj exponents: (xa)b=xab Peb tuaj yeem pom qhov tshwm sim no los ntawm kev sau nws ua cov khoom uas xa rov qab b times: (xa)b=xa×xa×⋯×xa⏟b times.

Ib qho piv txwv ntawm kev sib npaug exponential yog dab tsi?

Ib qho kev sib npaug exponential yog ib qho kev sib npaug nrog tus lej uas tus exponent (lossis) ib feem ntawm tus exponent yog qhov sib txawv. Piv txwv li, 3^x=81, 5^x-3 =625 , 6^{2y-7=121, thiab lwm yam yog ib co piv txwv ntawm exponential equations.}
