Txoj Kev 2 Multiplying Square Roots WithCoefficients

  1. Ntau cov coefficients. Ib tug coefficient yog ib tug lej nyob rau hauv pem hauv ntej ntawm lub radical kos npe.
  2. Ntau cov radicans.
  3. Qhia tawm cov squares zoo meej hauv radicand, yog tias ua tau.
  4. Ntau tus square cag ntawm lub zoo meej square los ntawm cov coefficient.

Yog li ntawd, koj puas tuaj yeem muab qhov tsis zoo square cag?

Hauv kub hauv paus teeb meem, nws yog ua tau muab ntau ntau ib tsis zoo nqi sij hawm nws tus kheej peb zaug thiab tau txais ib tsis zoo teb. Txawm li cas los xij, kev nyuaj siab yuav tshwm sim peb saib ib qho teeb meem xws li. Qhov no square cag teeb meem yog nug tus lej multiplied lub sij hawm nws tus kheej uas yuav muab cov khoom (lus teb) ntawm -16.

Kuj Paub, koj ua li cas yooj yim cov hauv paus plaub hau? Txoj Kev 1 Simplifying ib Square Root byFactoring

  1. Nkag siab txog factoring.
  2. Faib los ntawm tus lej tsawg tshaj plaws ua tau.
  3. Rewrite lub hauv paus square raws li ib tug multiplication teeb meem.
  4. Rov ua dua nrog ib tus lej ntxiv.
  5. Ua kom yooj yim los ntawm "rub tawm" tus lej.
  6. Muab cov lej ntau ua ke yog tias muaj ntau tshaj ib.

Ib yam li ntawd, tib neeg nug, koj tuaj yeem ntxiv cov hauv paus square?

Square cag tej zaum yuav ntxiv los ntawm kev hloov lawv mus rau lawv cov lej lej thiab tom qab ntawd ntxiv lawv, tab sis qhov tshwm sim tsis meej. Rau ntxiv square cag (radical expressions) raws nraim, koj tej zaum tsuas txo lawv thiab ces ntxiv cov ntsiab lus 'like' ( cov hauv paus plaub hau nrog tib tus lej raws li theradical, lossis √).

Tus nqi ntawm square root yog dab tsi?

Square, Lub voos xwmfab, Square hauv paus thiab Cubic hauv paus rau cov lej suav nrog 0- 100

Number x Square x2 Square Root x1/2
2 4 1.414
3 9 1.732
4 16 2.000
5 25 2.236
