Inqaku lezenzululwazi

Umxholo

• Imizekelo yokubhalwa kwesayensi

Inkqubo ye- Inqaku lezenzululwazi, ikwabizwa ngokuba Isaziso sokubonisa okanye ifom esemgangathweni, ikuvumela ukuba ubonakalise amanani amakhulu kakhulu okanye amancinci kakhulu ngendlela emfutshane nelula, eyenza lula ukubhala kunye nokunceda xa kufuneka wenze imisebenzi yezibalo ngala manani okanye uwafake kwiifomula okanye ii-equations.

Kukholelwa ukuba ibiyiyo Archimedes owazisa iindlela zokuqala ezikhokelele kumxholo wobhalo lwenzululwazi.

Inkqubo ye-amanani kubhalo lwenzululwazi zibhaliwe njengemveliso yenani elipheleleyo okanye inani lokugqibela phakathi kwe-1 kunye ne-10 kunye namandla esiseko se-10.

Ngale ndlela, ubhalo lwenzululwazi luphendula kule fomyula ilandelayo: n x 10^x o n x 10^-x. Njengenqubo esebenzayo, kunokuthiwa ukuguqula amanani angaphezu kwe-1 ukuya kwisayensi, kuya kufuneka ubeke isiphumlisi emva kwedijithi yokuqala kwaye ubale ukubala ngokujonga ukuba zingaphi iindawo ezishiyekileyo ngasekhohlo.

Ukuguqula amanani angaphantsi kwe-1 ukuya kubhalo lwenzululwazi, Kuya kufuneka ubeke isiphumlisi emva kwenani lesibini ukuya kwelokugqibela kwaye ubala i-eksponenti ngokuxhomekeke ekubeni zingaphi iindawo ekunene ezishiyekileyo, ibonakaliswe njengaleyo. Kwimizekelo enikwe apha ngasentla, inani lika-Avogadro liya kuba ngu-6.022 × 10²³ kunye nobunzima be-hydrogen ngu-1.66 × 10^-23.

Amanani kwi-notation yesayensi nayo inokubhalwa njenge-exponential notation. Umzekelo, 4 × 10⁸ Ingabhalwa njenge-4e + 8.

Ukuphindaphinda amanani kubhalo lwenzululwazi, kuya kufuneka phindaphinda amanani kwicala lasekhohlo, loo mveliso iphindaphindwe ngo-10 iphakanyisiwe kwisambuku sabakhupheli ngabanye. Ukwahlula amanani kubhalo lwezenzululwazi, kuya kufuneka uwahlule amanani asekhohlo, eso siphumo siphindaphindwe ngo-10 siphakanyisiwe ukukhupha abaxhasi.

Imizekelo yokubhalwa kwesayensi

Nayi imizekelo yamanani kwisayensi:

1. 7.6 x 10¹² Iikhilomitha (umgama phakathi kwelanga kunye nePluto kwindawo ekude kumjikelo wayo)
