Tirooyinka Dhaqaaqaya - 2
CAQABADDA
Soo hel lambar 4-god ah, ABCD, oo qancisa isla'egtan xiisaha leh marka aad dib u rogto tirooyinka:
ABCD x 4 = DCBA
SHARAXAADA
Baadh sababta aysan tani u dhici karin lambarrada ka yar 1000. Sidoo kale, raadi lambarro ka weyn 9,999 oo leh hantidan.
Notes
CAQABADDA
Maadaama ABCD lagu dhufto 4 ay soo saarto tiro 4-god ah, A waa inay noqotaa 1 ama 2. Sidoo kale, maadaama natiijada ku dhufashada D 4 ay leedahay hal god oo A ah, waan ognahay in A ay tahay inay siman tahay. Markaa A = 2. Isle'egtayadu hadda waa 2BCD x 4 = DCB2.
D x 4 waxay soo saartaa 2 macnaheedu waa in D uu yahay 3 ama 8. Ogsoonow in 4 jeer oo tiro ka weyn 2000 ay abuurto tiro ugu yaraan 8000 ah. Sidaa darteed, D waa inay noqotaa 8.
Isle'egtayadu hadda waa 2BC8 x 4 = 8CB2.
B waa inuu ka yar yahay 3, ama 2B x 4 wuxuu ka weynaan doonaa 8999. Marka la eego C8 x 4 oo la marayo tobanka qiima ee C, habka kaliya ee lagu heli karo qiimaha B ee xadkaas waa haddii C uu yahay 2 ama 7 B-na uu yahay 1. Sidaa darteed, waxaan haynaa laba lambar oo keliya oo aan hubinno: 2128 ama 2178.
Jawaabtu waa 2178!
SHARAXAADA
Macquulka muujinaya in tiradu ay tahay inay lahaato tiro sare oo 2 ah iyo tiro hoose oo 8 ah iyadoon loo eegin inta lambar ee tiradu leedahay.
Marka la eego lambarrada laba-godlaha ah, 28 ma shaqeyso. Lambarrada saddexda-godlaha ah, 2×8 uma shaqeyso qiimo kasta oo x ah.
Falanqaynta tirooyinka waaweyn waxay u badan tahay inay ka badan tahay inta aad jeclaan lahayd inaad akhrido. Waa kuwan tirooyinka soo socda: 21978, 219978, iyo 2199978.
