Walk the talk

I got a comment recently that my numbers have not walked for some recent time past.I am now showing they could walk the talk also.This is an imaginary conversation between numbers 2 and 5.
The younger member Y(2)started the talk.
Hello can we become friends?
Elder member E(5) replied.
Dont you know .we are already friends ,whenever I regenerate myself you are close by my side like in 5*5=25 and 25*5=625 etc.Also when I regenerate myself 5 times I become yourself in disguise..Check it 5*5*5*5*5=3125...3+1+2+5=11...1+1=2
Similarly when you regenerate yourself 5 times,you become myself in disguise....Check it.2*2*2*2*2=32...3+2=5
 I will reveal to you more about our friendship in our next conversation.

Using a set of scales for weighment

Suppose you have a set of scales useful for weighing any article.Suppose also that you are allowed to place the article on one side.and that weights are allowed to be placed only on the other side.Suppose you are required to weigh articles upto  80 kg.The question is what is the minimum number of weights required to weigh any article where they can weigh from 1kg upto 80 kg.I will wait for a response before giving the answer.
