Sayenzi notation

• Mienzaniso yesainzi notation

Iyo Sayenzi notation, inonziwo exponential notation kana yakajairwa fomu, inobvumidza iwe kuratidza nhamba hombe kwazvo kana diki kwazvo nenzira ipfupi uye yakapusa, izvo zvinoita kuti zvive nyore kunyora uye zvinobatsira kana uchifanira kuita masvomhu mashandiro nenhamba idzi kana kuzviisa mumafomula kana ma equation.

Zvinotendwa kuti ndizvo Archimedes uyo akaunza nzira dzekutanga dzakatungamira kupfungwa yesainzi notation.

Iyomanhamba musainzi notation iwo akanyorwa sechigadzirwa chehuwandu kana nhamba yedesimali pakati pe1 ne10 uye simba re base.

Nenzira iyi, notisation notation inopindura inotevera fomula: n x 10^x o n x 10^-x. Senzira inoshanda, zvinogona kutaurwa kuti kuti uchinje manhamba akakura kudarika 1 kuvesainzi, iwe unofanirwa kuisa comma mushure mekutanga manhamba uye kuverenga chinoburitswa zvichibva nenzvimbo dzakasiiwa kuruboshwe.

Kuti uchinje manhamba asingasviki 1 kune sainzi notation, Iwe unofanirwa kuisa comma mushure mechipiri uye yekupedzisira manhamba uye kuverenga chinongedzo zvinoenderana nenzvimbo ngani kurudyi dzakasiiwa, inoratidzwa seisina kunaka. Mune iyo mienzaniso yakapihwa pamusoro, nhamba yaAvogadro ichave 6.022 × 10²³ uye huremu hwehydrogen i1.66 × 10^-23.

Numeri musainzi notation inogona zvakare kunyorwa seyakanyanya exponential. Semuenzaniso, 4 × 10⁸ inogona kunyorwa sa4e + 8.

Kuti uwedzere zviyero musainzi notation, unofanirwa wedzera nhamba kuruboshwe, Chigadzirwa ichocho chinobva chawedzeredzwa negumi chinokwidzwa kusvika kuhuwandu hweanoburitsa pachena. Kupatsanura manhamba musainzi notation, iwe unofanirwa kugovanisa manhamba ari kuruboshwe, mhedzisiro yacho yakawedzeredzwa negumi yakasimudzwa pakubvisa kwevanotsanangudza.

Mienzaniso yesainzi notation

Heano mienzaniso yezviverengero musainzi notation:

1. 7.6 x 10¹² makiromita (chinhambwe pakati pezuva naPluto kunzvimbo iri kure munzira yayo)
