Yog li, nyob rau hauv thiaj li yuav paub uas yog algebraic kev qhia yog nyob rau hauv nws daim ntawv yooj yim tshaj plaws , koj yuav tsum paub tseeb tias koj tsis muaj peev xwm faib nws ntxiv. Txij li thaum koj tuaj yeem tshem (X + Y) ntawm qhov sib npaug, (X^2 - Y^2) / (X + Y) = (X - Y), uas yog daim ntawv yooj yim tshaj plaws ntawm no kev qhia.

Hais txog qhov no, dab tsi yog qhov kev qhia hauv daim ntawv yooj yim tshaj plaws?

Feem ntau, ib kev qhia yog nyob rau hauv daim ntawv yooj yim tshaj plaws thaum nws yog qhov yooj yim los siv.

Ib tug kuj nug, koj yuav daws cov lus hais li cas? Nov yog ib qho piv txwv ntawm qhov kev txiav txim ntawm kev ua haujlwm li cas:

1. (3 + 5)² x 10+ 4.
2. Ua ntej, ua raws li P, kev ua haujlwm hauv kab lus:
3. = (8)² x 10+ 4.
4. Tom qab ntawd, ua raws li E, kev ua haujlwm ntawm tus exponent:
5. Luas = 64 x 10 + 4.
6. Tom ntej no, ua multiplication:
7. = 640 + 4.
8. Thiab kawg, ua ntxiv:

Ntawm no, koj yuav qhia li cas yog ib feem yog nyob rau hauv daim ntawv yooj yim?

A feem yog nyob rau hauv nws daim ntawv yooj yim yog tus lej (tus lej saum toj kawg nkaus) thiab tus lej (tus lej hauv qab) tsis muaj qhov sib xws (tsis suav nrog 1). Qhov no txhais tau hais tias tsis muaj tus lej koj tuaj yeem faib ob qho tib si sib npaug. Yog li, mus xyuas yog ib feem yog nyob rau hauv nws daim ntawv yooj yim tshaj plaws , koj yuav tsum tau kuaj xyuas cov yam tseem ceeb.

Coefficients yog dab tsi?

Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm polynomial, series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Piv txwv li, yog tias y raug suav tias yog ib qho parameter hauv cov lus hais saum toj no, qhov coefficient ntawm x yog −3y, thiab qhov tsis tu ncua coefficient yog 1.5 + y.
