Chiyambi pansi pa chizindikiro cha muzu

M'bukuli, tiwona momwe tingalowetse nambala (ochulukitsa) kapena chilembo pansi pa chizindikiro cha lalikulu ndi mphamvu zapamwamba za muzu. Chidziwitsocho chikuphatikizidwa ndi zitsanzo zothandiza kuti mumvetsetse bwino.

Lamulo lolowera pansi pa chizindikiro cha mizu

square root

Kuti mubweretse nambala (chinthu) pansi pa chizindikiro cha square root, iyenera kukwezedwa ku mphamvu yachiwiri (mwa kuyankhula kwina, squared), kenako lembani zotsatira pansi pa chizindikiro cha mizu.

Chitsanzo 1: Tiyeni tiyike nambala 7 pansi pa mzu wa lalikulu.

Kusankha:

1. Choyamba, tiyeni tiyike nambala yomwe tapatsidwa: 7² = 49.

2. Tsopano tingolemba nambala yowerengedwa pansi pa muzu, mwachitsanzo, tipeza √49.

Mwachidule, mawu oyamba pansi pa chizindikiro cha mizu akhoza kulembedwa motere:

Zindikirani: Ngati tikukamba za chochulukitsira, timachichulukitsa ndi mawu omwe alipo kale.

Chitsanzo 2: kuyimira malonda 3√5 kwathunthu pansi pa muzu wa digiri yachiwiri.

nth mizu

Kuti tibweretse nambala (chinthu) pansi pa chizindikiro cha mphamvu za kiyubiki ndi zapamwamba za muzu, timakweza chiwerengerochi ku sitepe yoperekedwa, kenaka tumizani zotsatirazo kuzinthu zazikulu.

Chitsanzo 3: Tiyeni tiyike nambala 6 pansi pa muzu wa cube.

Chitsanzo 4: imagine product 2⁵√3 pansi pa muzu wa digiri ya 5.

Nambala yolakwika/yochulukitsa

Mukalowa nambala yolakwika / chochulukitsa pansi pa muzu (zilibe digirii), chizindikiro chochotsera nthawi zonse chimakhalabe patsogolo pa chizindikiro cha mizu.

Mwachitsanzo 5

Kulowetsa chilembo pansi pa muzu

Kuti tibweretse chilembo pansi pa chizindikiro cha mizu, timapita mofanana ndi manambala (kuphatikizapo zoipa) - timakweza kalatayi pamlingo woyenera, ndikuwonjezera ku mawu a mizu.

Mwachitsanzo 6

Izi ndi zoona pamene p> 0, ngati p ndi nambala yotsutsa, ndiye chizindikiro chochotsera chiyenera kuwonjezeredwa musanayambe chizindikiro.

Mwachitsanzo 7

Tiyeni tilingalire vuto lina lovuta kwambiri: (3 + √8) √5.

Kusankha:

1. Choyamba, tidzalowetsa mawuwa m'mabulaketi pansi pa chizindikiro cha mizu.

2. Tsopano molingana ndi ife tikweza mawuwo (3 + √8) mu lalikulu.

Zindikirani: masitepe oyamba ndi achiwiri akhoza kusinthana.

3. Zimangotsala kuti muchulukitse pansi pa muzu ndi kukulitsa mabakiti.
