Kordhinta Badeecadaha 16
Fiiri siyaabaha aad 16 ugu kala qaybin karto tirooyin aad markaa ku dhufan karto si aad u hesho badeecad weyn intii suurtagal ah. Qorista 16 = 10 + 6 waa bilow, laakiin 16 = 6 + 5 + 5 ayaa ka fiican. Ma ka sii fiicnaan kartaa?
16 = 10 + 6 iyo 10 x 6 = 60
16 = 6 + 5 + 5 iyo 6 x 5 x 5 = 150
CAQABADDA
Waa maxay badeecada ugu weyn ee aad samayn karto adigoo 16 u kala qaybinaya tirooyin?
SHARAXAADA
Sidee istaraatiijiyaddaadu isu beddeshaa haddii aad 16 ku beddesho 20, 50, ama 100?
Notes
Caqabadda iyo Sahaminta
Aan ku bilowno inaan eegno tusaalooyin ku beddelaya 16 tirooyin yar yar. Helitaanka khibraddan had iyo jeer waa hab wanaagsan oo lagu bilaabo, badanaana waqti dheer ma qaadato.
1 = 1 => 1
2 = 2 => 2
3 = 3 => 3
4 = 2 + 2 ama kaliya 4 => 4
5 = 2 + 3 => 2 x 3 = 6
6 = 3 + 3 => 3 x 3 = 9
7 = 2 + 2 + 3 => 2 x 2 x 3 = 12
8 = 2 + 3 + 3 => 2 x 3 x 3 = 18
9 = 3 + 3 + 3 => 3 x 3 x 3 = 27
10 = 2 + 2 + 3 + 3 => 2 x 2 x 3 x 3 = 36
Markaad eegto tusaalooyinkan, waxaa soo baxaya qaab lagu kala qaybinayo tirooyin waaweyn.
- Tiro kasta oo ka weyn 4 waa in lagu beddelaa tirooyin yaryar!
- Waligaa ha isticmaalin 1 ilaa aad haysato wax doorasho ah.
- Isticmaal 2 + 2 halkii aad ka isticmaali lahayd 4. Waxay bixiyaan natiijo isku mid ah, laakiin way fududahay in la arko sida wax loo hagaajiyo marka la eegayo 2 halkii laga eegi lahaa 4.
- Had iyo jeer ku beddel 2 + 2 + 2, taasoo siinaysa 2 x 2 x 2 = 8, oo siinaysa 3 + 3, taasoo siinaysa 3 x 3 = 9.
Iyadoo la adeegsanayo xeerarkan, istaraatiijiyad guud ayaa soo baxaysa si loo weeraro tiro kasta.
- Haddii tiradu tahay mid siman, u qor wadarta 2. Haddii tiradu tahay mid aan caadi ahayn, u qor 3 oo lagu daray wadarta 2.
- Ku beddel koox kasta oo saddex 2 ah koox laba 3 ah.
Iyadoo waxaas oo dhan la meel dhigay, waxaan diyaar u nahay inaan xallino dhibaatada.
16 = 2 + 2 + 2 + 2 + 2 + 2 + 2 = 2 + 2 + 3 + 3, taasoo bixinaysa natiijo ah 2 x 2 x 3 x 3 x 3 = 324.
Tirooyinka kale, waxaan haynaa:
20 = 10 x 2 = 2 + 3 x (3 x 2) = 2 + 3 x (2 x 3) = 2 + 6 x 3, taasoo bixinaysa 2 x 3^6 = 2 x 729 = 1458.
50 = 25 x 2 = 2 + 8 x (3 x 2) = 2 + 8 x (2 x 3) = 2 + 16 x 3, taasoo bixinaysa 2 x 3^16.
100 = 50 x 2 = 2 x 2 x 16 x (3 x 2) = 2 + 2 + 16 x (2 x 3) = 2 x 2 + 32 x 3, taasoo bixinaysa 4 x 3^32.
