Kuyerwa kana kuverenga mufizikisi kunobva pahukuru hudiki hwezvimedu, senge huremu hweerekitironi, kusvika pahukuru hukuru, senge huremu hwenyika. Kunyora mhedzisiro yekuyerwa kwezvinhu zvikuru, semuenzaniso huremu hwenyika hunosvika 6,000,000,000,000,000,000,000,000 kg kana mhedzisiro yekuyerwa kwezvimedu zvidiki, semuenzaniso huremu hweerekitironi hunosvika 0,000,000,000,000,000,000,000,000,000,000,000,000,000.911 kg inoda nzvimbo yakakura uye inowanzonyorwa zvisirizvo. Kuti tikunde dambudziko iri, tinogona kushandisa notation yesainzi.
Mukunyora kwesainzi, mhedzisiro yekuyera inoratidzwa se: a, ….. x 10n
Information :
a inhamba yechisikigo inotangira pa1 kusvika pa9
n inonzi exponent uye inhamba yakakwana
10n ratidza kurongeka
Mitemo yekunyora mhedzisiro yekuyera uchishandisa notation yesainzi
a) Kana muine nhamba dzinopfuura gumi, fambisai poindi yedesimali kuruboshwe. Chiratidzo chacho chiri positive.
Muenzaniso:
210000000 m = 2,1 x 108 m
62400,1 m = 6,24001 x 104 m = 6,2 x 104 m
33000 m = 3,3 x 104 m
b) Kana muine nhamba dziri pasi pe1, fambisai poindi yedesimali kurudyi. Chiratidzo chacho chiri negative.
Muenzaniso:
0,0045 m = 4,5 x 10-3 m
0,000000234 m = 2,34 x 10-7 m = 2,3 x 10-7 m
0,0001075 m = 1,075 x 10-4 m = 1,1 x 10-4 m
