Multiplicative Inverse of a Negative Number Ib yam li rau ib tus lej zoo, qhov khoom ntawm tus lej tsis zoo thiab nws qhov kev sib raug zoo yuav tsum sib npaug rau 1. Yog li, qhov sib txawv ntawm qhov sib txawv ntawm txhua tus lej tsis zoo yog nws qhov sib txawv. Piv txwv li, (-6) × (-1/6)=1, yog li ntawd, qhov sib txawv inverse ntawm -6 yog -1/6.
Puas yog qhov sib npaug ntawm tus lej tsis zoo?
Ib yam khoom tseem ceeb ntawm kev sib hloov pauv yog tias thaum tus lej sib npaug nrog nws qhov sib npaug lossis sib npaug sib npaug, peb tau 1. tsuas yog. Li no, peb cov lus teb yog kev xaiv B) Tus lej tsis zoo.
Yuav hloov pauv hloov pauv tsis zoo?
Kuv muaj nuj nqi hauv qab no los xam cov modular multipplication inverse ntawm tus lej n muab tus lej modulo p. Yog tias n yog qhov zoo, nws zoo, tab sis yog tias n yog qhov tsis zoo nws muab ib txwm 0.
Dab tsi yog qhov sib npaug ntawm qhov tsis zoo 3?
Yog li qhov sib npaug ntawm 3 yog 1/3.
Yuav ua li cas yog txoj cai ntawm kev sib hloov pauv?
Cov cuab yeej hloov pauv ntawm kev sib faib hais tias yog tias koj muab tus lej los ntawm nws qhov sib txawv, kuj hu ua qhov sib txawv ntawm qhov sib txawv, khoom yuav yog 1.
