Ib yam li ntawd, puas exponents tshem tawm cov hauv paus square?
Qhov ntawd txhais tau tias yog tias koj muaj qhov sib npaug nrog cov hauv paus plaub hau hauv nws, koj tuaj yeem siv qhov "squaring", lossis exponents , tshem tawm cov hauv paus plaub hau.
Kuj Paub, tus nqi ntawm square root yog dab tsi? A square cag ntawm tus lej yog a tus nqi uas, thaum muab faib los ntawm nws tus kheej, muab tus lej. Piv txwv li: 4 × 4 = 16, a square cag ntawm 16 yog 4. Nco ntsoov tias (−4) × (−4) = 16 too, ces −4 kuj yog ib square cag ntawm 16. Lub cim yog √ uas ib txwm txhais tau tias qhov zoo square cag.
Tsis tas li ntawd, lub zog ntawm lub hauv paus square yog dab tsi?
Lub hauv paus square yog ces sau raws li lub hwj chim ntawm ib nrab: x½. Yog li ntawd, ib tug fractional exponent qhia tias qee lub hauv paus yuav tsum tau noj. Ib qho 1/2 feem qhia tias nws yog lub hauv paus square, thiab 1/3 feem qhia tias nws yog lub voos xwmfab, thiab lwm yam.
Koj ntxiv thiab rho tawm cov radicals li cas?
Rau ntxiv los yog tshem tawm cov radicals , cov indices thiab dab tsi nyob rau hauv lub radical (hu ua radicand) yuav tsum yog tib yam nkaus. Yog tias qhov ntsuas thiab radicans zoo ib yam, ces ntxiv los yog rho tawm cov ntsiab lus nyob rau hauv pem hauv ntej ntawm txhua tus nyiam radical . Yog tias cov indices lossis radicands tsis zoo ib yam, ces koj ua tsis tau ntxiv los yog rho tawm tus radicals.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Puas yog cov plaub hau daj lossis cov plaub hau xim av muaj ntau dua?
Cov plaub hau xim av yog qhov tseem ceeb tshaj cov plaub hau daj. Cov me nyuam uas muaj ib tug xim av-haired allele thiab ib tug blonde-haired allele yuav nthuav cov plaub hau xim av thiab. Tsuas yog cov uas muaj ob lub ntsej muag plaub hau daj yuav muaj cov plaub hau daj
Peb yuav daws li cas rau lub hwj chim?
Lub zog sib npaug ua haujlwm (J) faib los ntawm lub sijhawm (s). Lub SIunit rau lub zog yog watt (W), uas sib npaug 1 joule ntawm tus neeg ua haujlwm thib ob (J / s). Lub zog tuaj yeem ntsuas hauv ib chav hu ua thehorsepower. Ib lub zog horsepower yog tus nqi ntawm kev ua haujlwm ib tus nees tuaj yeem ua hauv 1 feeb, uas sib npaug 745 watts ntawm lub zog
Yuav ua li cas koj xam mus rau plaub lub hwj chim?
Hauv kev suav lej thiab lej, plaub lub zog ntawm tus lej n yog qhov tshwm sim ntawm kev muab plaub qhov piv txwv ntawm n ua ke.So: n4 = n × n × n × n. Fourthpowers kuj yog tsim los ntawm kev sib npaug ntawm tus lej los ntawm nws covcube
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
