Ko ngā inenga, ngā tātaitanga rānei i roto i te ahupūngao, mai i ngā rahi matūriki tino iti, pērā i te papatipu o te irahiko, ki ngā rahi tino nui, pērā i te papatipu o te whenua. Ko te tuhi i ngā hua o ngā inenga o ngā mea tino nui, hei tauira, ko te papatipu o te whenua he tata ki te 6.000.000.000 kg, ko ngā hua rānei o ngā inenga o ngā matūriki tino iti, hei tauira, ko te papatipu o te irahiko he tata ki te 000.000.000.000.000. Ko te 0,000.000.000.000.000.000.000.000.000.000.911 kg he wāhi nui, ā, he maha ngā wā ka hē te tuhi. Hei whakakore i tēnei raruraru, ka taea e tātou te whakamahi i te tuhi pūtaiao.
I roto i ngā tuhipoka pūtaiao, ko te hua ine e whakaatuhia ana penei: a, ….. x 10n
Ngā Mōhiohio:
he tau tūturu a a mai i te 1 ki te 9
ka kiia a n ko te taupū, ā, he tauoti
10n whakaatu i te raupapa
Ngā ture mō te tuhi i ngā hua ine mā te whakamahi i ngā tuhipoka pūtaiao
a) Mō ngā tau neke atu i te 10, nekehia te ira tekau ki te taha maui. He pai te taupū.
Tauira:
210000000 mita = 2,1 x 108 m
62400,1 mita = 6,24001 x 104 m = 6,2 x 104 m
33000 mita = 3,3 x 104 m
b) Mō ngā tau iti iho i te 1, nekehia te ira tekau ki te taha matau. He tōraro te taupū.
Tauira:
0,0045 mita = 4,5 x 10-3 m
0,000000234 mita = 2,34 x 10-7 m = 2,3 x 10-7 m
0,0001075 mita = 1,075 x 10-4 m = 1,1 x 10-4 m
