【Do you know an almighty pair of scales?】

《A question in which a sense of mathematic is necessary for us》

...but I’m not sure the relation between the number which is expressed with the binary system, 1101 and three kinds of weight, 1 gram, 4 gram and 8 gram.

The author continued, all the numbers in decimal system are expressed with those in the binary system, we have only to prepare for every weight of binary system one by one. It’s enough. Why?

To return to our main subject, I’ll start again.

But for example, how about in a case when we have to prepare for a weight of 4 to nth power?
