Cov Zero Product Property hais tias yog ab = 0, ces yog a = 0 los yog b = 0, los yog ob qho tib si a thiab b yog 0. khoom ntawm yam sib npaug xoom , ib los yog ntau tshaj ntawm cov yam tseem ceeb yuav tsum sib npaug xoom . Thaum lub polynomial yog factored, teem txhua yam sib npaug rau xoom thiab daws lawv nyias.
Ua raws li qhov no hauv kev txiav txim siab, yuav ua li cas lub zero cov cuab yeej ua haujlwm?
Cov Zero Product Property . Cov Zero Product Property yooj yim hais tias yog ab = 0, ces yog a = 0 los yog b = 0 (los yog ob qho tib si). A khoom ntawm yam yog xoom yog tias thiab tsuas yog ib lossis ntau qhov ntawm cov xwm txheej xoom . Qhov no yog qhov tshwj xeeb tshaj yog thaum daws cov kab zauv sib npaug.
Tsis tas li ntawd, distributive property txhais li cas? Cov distributive khoom yog ib qho ntawm feem ntau siv khoom hauv lej. Feem ntau, lo lus no hais txog tus faib khoom ntawm multiplication uas hais tias lub. Txhais : Cov faib khoom cia koj muab cov lej sib npaug los ntawm kev sib faib txhua qhov ntxiv sib cais thiab tom qab ntawd ntxiv cov khoom.
Hauv qhov no, vim li cas ho tsis tuaj yeem 0 hauv ib qho kev sib npaug plaub npaug?
Yog ib quadratic equation ax^2+bx+c= 0 muaj ntau tshaj ob lub hauv paus, ces nws dhau los ua tus kheej a=b=c= 0 . Sai li "a = 0 ", koj tsis muaj 2nd degree lawm kev sib npaug . Thiab, koj daim duab yuav tsis yog parabola. Yog a=b=c= 0 , ces sab laug ntawm lub kev sib npaug ua 0.
Dab tsi yog cov cuab yeej sib npaug ntawm xoom?
Cov multiplication khoom hais tias cov khoom ntawm ib tus lej thiab xoom yog xoom . Nws tsis muaj teeb meem dab tsi tus lej yog, thaum koj muab faib rau xoom ,koj tau xoom raws li cov lus teb.

Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog xoom xoom thiab vim li cas thiaj hu ua li ntawd?
Tsis muaj xoom yog - 273.15 degrees Celsius, -459.67 degrees Fahrenheit, thiab 0 Kelvin. Yog li hu ua vim nws yog lub ntsiab lus ntawm qhov tseem ceeb ntawm cov xwm txheej muaj qhov kev vibrational tsawg tsawg, khaws cia tsuas yog quantum mechanical, xoom-point zog-induced particle suab
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
Dab tsi yog tus nqi lees paub ntawm tus xoom xoom?
Los ntawm kev pom zoo thoob ntiaj teb, xoom xoom raug txhais raws li qhov tseeb; 0 K ntawm Kelvin nplai, uas yog qhov ntsuas kub ntawm qhov ntsuas kub (qhov tseeb); thiab -273.15 degrees Celsius ntawm qhov ntsuas Celsius
