it's stupid nigga

>>7854662

where do you see a problem?
>>
>>7854666
You are retarded if can't find it.
>>
>>7854666
>>7854743
There's multiple problems with this proof
>>
>>7854813

Lets hear them, then
>>
>>7854813
you mean in the language or in that it's not valid?
>>
>>7854662
did all you already observe this?

am I stupid for liking this?
>>
>>7854813
>>7854827
>>7855050
It's not well written.

Also (13)^5 doesn't end in 13
>>
Is it only supposed to work with natural numbers between 0 and 9?
>>
>>7855078

13^5
=371293

are you baiting?
>>
>>7855113

no, i proved it works with all integers. If you simply flip the signs in the proof you will also see that it works for negative numbers too.
>>
>>7855228
n = 13

>last digit ends in n

Only way to take this is that last digits end in 13, which it doesnt.

If you think I don't see that it ends in 3 you're mistaken, but that's not what the proposition states
>>
>>7855248

Its a lack of rigour in my phrasing, but its heavily implied.
>>
>>7855256
The cool thing about math is that implications can be stated and proved.

There is literally no reason a reader should make assumptions.
>>
>>7855256
OP what's this "TD" bullshit. Do everything modulo 10.
>>
Interesting OP. Never noticed this before.
>>
>>7854658
89^5 = 5584059449
Your proof is wrong. I think you should try to prove that the integer in the position of the units determines the final digit, which is kinda obvious.
>>
>>7855278

Not OP but in my textbooks Ive seen it written in TD notation.
>>
>>7855291

See >>7855256 . Was just careless phrasing.

fixed
