Kev piav qhia: Tus degree yog tus nqi siab tshaj plaws ntawm tus lej ntawm qhov sib txawv hauv cov polynomial . Ntawm no, qhov siab tshaj plaws exponent yog x5, yog li qib yog 5.
degree txhais li cas hauv polynomials?
Qhov degree ntawm polynomial yog tus lej loj tshaj plaws ntawm ib qho ntawm nws qhov sib txawv(rau ib qho sib txawv), lossis qhov loj tshaj plaws ntawm cov lej ntawm cov sib txawv hauv ib lub sijhawm (rau ntau qhov sib txawv). Ntawm no, lo lus nrog tus lej loj tshaj plaws yog, yog li qib ntawm tag nrho polynomial yog 6.
Dab tsi yog qhov piv txwv ntawm polynomial?
Qhov degree ntawm polynomials hauv ib qhov sib txawv yog lub zog siab tshaj plaws ntawm qhov sib txawv hauv qhov qhia txog algebraic . Piv txwv li, hauv kab zauv hauv qab no: x2+2x+4. Qhov degree ntawm qhov sib npaug yog 2. i.e. lub zog siab tshaj plaws ntawm qhov sib txawv hauv kab zauv.
degree 4 polynomial yog dab tsi?
In algebra, a quartic function yog ib txoj haujlwm ntawm daim ntawv. qhov twg a yog nonzero, uas yog txhais los ntawm polynomial ntawm degree plaub, hu ua quartic polynomial. Ib qho kev sib npaug quartic, lossis qhov sib npaug ntawm plaub degree, yog qhov sib npaug uas sib npaug ntawm quartic polynomial rau xoom, ntawm daim ntawv. qhov twg ≠ 0.
Qib 5 yog dab tsi?
degree ntawm 5 yog 0.
