Rau sau dua tshiab tus negative exponent raws li apositive exponent , coj qhov sib thooj ntawm lub hauv paus a. Nyem qhov no. Saib ntawm qhov qhia thiab nrhiav qhov negativeexponent . Rau sau dua tshiab tus negative exponent raws li apositive exponent , coj tus reciprocal ntawm lub basea.
Kuj paub, kuv yuav hloov tus lej tsis zoo rau qhov zoo li cas?
Negative Exponent Txoj cai:, qhov no hais tias tsis zoo exponents nyob rau hauv tus lej tau tsiv mus rau tus denominator thiab ua zoo exponents . Negativeexponents nyob rau hauv tus denominator tau tsiv mus rau tus lej thiab ua zoo exponents . Tsuas yog txav lub negativeexponents.
Tom qab ntawd, lo lus nug yog, yuav ua li cas tshwm sim thaum tus exponent tsis zoo? A negative exponent tsuas yog txhais tau hais tias lub hauv paus ison tsis ncaj ncees lawm sab ntawm kab feem, yog li koj yuav tsum tig lub hauv paus mus rau sab nraud. Piv txwv li, "x–2"(pronounced as "ecks to the minustwo") tsuas yog txhais tau tias "x2, tab sis hauv qab, raws li hauv 1 x 2frac{1}{x^2} x21 ".
Kuj nug, ua li cas koj hloov tus exponent tsis zoo rau hauv ib feem?
A negative exponent Nws suav nrog kev noj tus lej inverse ntawm tus lej, tom qab ntawd muab nws los ntawm nws tus kheej thaum nws nyob hauv tus lej ntawm tus lej feem . Yog tias negative exponent yog nyob rau hauv tus denominator twb, peb tseem ua tus inverse, uas txhais tau tias txav lub sij hawm mus rau tus zauv.
Tus lej tsis zoo txhais li cas?
A negative exponent txhais tau hais tias pes tsawg zaus todivided los ntawm tus lej. Piv txwv: 8-1 Luas = 1/8 = 0.125. Los yog ntau qhov sib faib: Piv txwv: 5-3 = 1 ÷ 5 ÷ 5 ÷ 5 =0.008.
