Muyeso kapena mawerengedwe mu fizikisi amayambira pa tinthu tating'ono kwambiri, monga kulemera kwa elekitironi, mpaka kukula kwakukulu kwambiri, monga kulemera kwa dziko lapansi. Kulemba zotsatira za muyeso wa zinthu zazikulu kwambiri, mwachitsanzo kulemera kwa dziko lapansi ndi pafupifupi 6,000,000,000,000,000,000,000,000,000 kg kapena zotsatira za muyeso wa tinthu tating'ono kwambiri, mwachitsanzo kulemera kwa elekitironi ndi pafupifupi 0,000,000,000,000,000,000,000,000,000,000,000,000,000.911 kg imafuna malo akuluakulu ndipo nthawi zambiri imalembedwa molakwika. Kuti tithetse vutoli, tingagwiritse ntchito zolemba zasayansi.
Mu zolemba zasayansi, zotsatira za muyeso zimafotokozedwa motere: a, ….. x 10n
Zambiri:
a ndi nambala yachilengedwe kuyambira 1 mpaka 9
n amatchedwa exponent ndipo ndi nambala yonse
10n onetsani dongosolo
Malamulo olembera zotsatira za muyeso pogwiritsa ntchito zolemba zasayansi
a) Pa manambala opitilira 10, sunthani mfundo ya decimal kumanzere. Choyimira ndi chabwino.
Chitsanzo:
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) Pa manambala ochepera 1, sunthani mfundo ya decimal kumanja. Chiwonetserocho ndi negative.
Chitsanzo:
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
