minus-squareaffiliate@lemmy.worldlinkfedilinkarrow-up2arrow-down1·1 year agoi thought they meant 20 + 1, but this makes way more sense
minus-squareBlueMagma@sh.itjust.workslinkfedilinkarrow-up5·edit-21 year agoBrilliant, now I wonder what ages this works for, I figured only 1 and 2, but then I realised we could write the father’s age in other bases… 1 = 2^0 (20 b10) 2 = 2^1 (21 b10) 3 = 3^1 (31 b7 = 22) 6 = 6^1 (61 b4 = 25) if they are lucky the grand father will be 61 that year :-D 8 = 2^3 (23 b12 =27) 9 = 9^1 (91 b3 = 28) 14 = 14^1 (141 b4 = 33)
minus-squareaDogCalledSpot@lemmy.ziplinkfedilinkEnglisharrow-up1·1 year agoYou have mistakes in a few of those. The number “61” doesnt exist in b4. 25b10 in b4 is “121”. Similar problem with 91b3 and 141b4.
minus-squareBlueMagma@sh.itjust.workslinkfedilinkarrow-up1·edit-21 year agoIndeed, I was so focused on the algebraic side I didn’t even think about it :-D I was computing 6*4+1=25

minus-squareCatsrules@lemmy.mllinkfedilinkarrow-up2arrow-down1·edit-21 year agoAhh yes your right, my bad. I was thinking the power was equal to her age but it is actually -1 her age. I was doing 2^3 when it should have been 2^2. I guess that is what I get when I don’t show my work. Dang math teacher was right.
minus-squarejack@monero.townlinkfedilinkarrow-up1·1 year agoAnd I thought you were making a follow-up joke to mine…

2^1

Brilliant, now I wonder what ages this works for, I figured only 1 and 2, but then I realised we could write the father’s age in other bases…
1 = 2^0 (20 b10)
2 = 2^1 (21 b10)
3 = 3^1 (31 b7 = 22)
6 = 6^1 (61 b4 = 25) if they are lucky the grand father will be 61 that year :-D
8 = 2^3 (23 b12 =27)
9 = 9^1 (91 b3 = 28)
14 = 14^1 (141 b4 = 33)

Poor kid going from 2 to 8 in 1 year.
You mean 2 -> 4?
2^2 = 4

Haha, no.
