• Izibonelo zokubhalwa kwesayensi

I- Ukuphawula ngokwesayensi, obizwa nangokuthi isichasiselo somchazi noma ifomu elijwayelekile, ikuvumela ukuthi uveze izinombolo ezinkulu kakhulu noma ezincane kakhulu ngendlela efushane futhi elula, eyenza ukubhala kube lula futhi kusize lapho kufanele wenze imisebenzi yezibalo ngalezi zinombolo noma uzifake kumafomula noma izibalo.

Kukholakala ukuthi bekuyiyo Ama-Archimedes owethula izindlela zokuqala ezaholela kumqondo wokubhalwa kwesayensi.

I-izinombolo ekubalweni kwesayensi zibhalwe njengomkhiqizo wenombolo ephelele noma yedesimali phakathi kuka-1 no-10 namandla esisekelo esingu-10.

Ngale ndlela, i-notation yesayensi iphendula ifomula elandelayo: n x 10^x o n x 10^-x. Njengenqubo esebenzayo, kungashiwo ukuthi ukuguqula izibalo ezinkulu kune-1 ziye ekubhaleni isayensi, kufanele ubeke ukhefana ngemuva kwedijithi yokuqala bese ubala i-eksponenti ngokuya ngokuthi zingaki izindawo ezisele ngakwesobunxele.

Ukuguqula izibalo ezingaphansi kuka-1 zibe isayensi, Kufanele ubeke ukhefana ngemuva kwedijithi yesibili kuya ekugcineni bese ubale i-eksponenti ngokuya ngokuthi zingaki izindawo ezingakwesokudla ezisele, ivezwe njengephikisayo. Ezibonelweni ezinikezwe ngenhla, inombolo ka-Avogadro ingaba ngu-6.022 × 10²³ futhi isisindo se-hydrogen singu-1.66 × 10^-23.

Izinombolo ekubalweni kwesayensi nazo zingabhalwa njengombhalo ochazayo. Isibonelo, i-4 × 10⁸ ingabhalwa njengo-4e + 8.

Ukuphindaphinda izibalo ekubalweni kwesayensi, kufanele phindaphinda izinombolo ohlangothini lwesobunxele, lowo mkhiqizo ube usuphindaphindwa ngo-10 okhushulwe waba yisamba sezichasisi ezingazodwana. Ukwehlukanisa izibalo ekubhalweni kwesayensi, kufanele uhlukanise izinombolo ezisohlangothini lwesobunxele, lowo mphumela uphindaphindwe ngo-10 ophakanyiselwe ekususeni kwabakhiphi.

Izibonelo zokubhalwa kwesayensi

Nazi izibonelo zezibalo ekubalweni kwesayensi:

1. 7.6 x 10¹² amakhilomitha (ibanga phakathi kwelanga noPluto endaweni ekude kakhulu ekuzungezeni kwalo)
2. 1.41 x 10²⁸ ama-cubic metres (ivolumu yelanga).
3. 7.4 x 10¹⁹ amathani (isisindo senyanga)
4. 2.99 x 10⁸ amamitha / isekhondi (isivinini sokukhanya ku-vacuum)
