Cov degree ntawm ib tug polynomial qhia yog lub siab tshaj plaws lub hwj chim (exponent) ntawm tus kheej cov nqe lus uas ua rau thepolynomial. Rau cov ntsiab lus nrog ntau qhov sib txawv, lub hwj chim (exponent) ntawm lub sij hawm yog qhov suav ntawm lub hwj chim (exponents) ntawm cov hloov pauv uas ua rau lub sij hawm.
Yog li ntawd, dab tsi yog txhais los ntawm degree ntawm kev sib npaug?
DEGREE NTAWM AN EQUATION . Cov degree ntawm ib kev sib npaug uas tsis muaj ntau tshaj ib qho kev sib txawv hauv txhua lub sij hawm yog tus exponent ntawm lub hwj chim siab tshaj plaws uas qhov sib txawv ntawm qhov tshwm sim hauv kev sib npaug.
Kuj Paub, qhov degree ntawm kev sib npaug plaub npaug yog dab tsi? Hauv lej, peb txhais a quadratic equation as ib kev sib npaug ntawm degree 2, lub ntsiab lus tias qhov siab tshaj plaws ntawm qhov kev ua haujlwm no yog 2. Tus qauv qauv ntawm a plaub fab yog y = ax^2 + bx + c, qhov twg a, b, thiab c cov lej thiab a tsis tuaj yeem yog 0. Piv txwv ntawm quadratic equations y = x^2 + 3x + 1.
Hais txog qhov no, koj pom qhov degree ntawm kev ua haujlwm li cas?
Lub zog ntawm lub sij hawm loj tshaj plaws yog lub degree ntawm polynomial. Rau nrhiav degree ntawm ib tug polynomial nrog ntau qhov sib txawv, sau cov lus qhia, tom qab ntawd ntxiv cov degree ntawm variables nyob rau hauv txhua lub sij hawm. Lub hwj chim ntawm lub sij hawm loj tshaj plaws yog koj cov lus teb!
Koj yuav txheeb xyuas qhov degree ntawm polynomial li cas?
Rau nrhiav qhov degree ntawm polynomial , koj thawj zaug txheeb xyuas txhua lub sij hawm [term yog piv txwv], li ntawd nrhiav degree ntawm txhua lub sij hawm koj ntxiv covexponents.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
