Should the weight of the digit be the degree of the base of the number system in which the number is written?

Question

binary code

Let's say, can the weight of a bit of a binary number be, for example, 30, or 10? I'm right? I can’t prove to the teacher in any way that the weight of the discharge should be a deuce to a certain extent.

Answer 1

According to the definition from Wikipedia , the weight of the digit is a factor by which the value of the digit in a given number system must be multiplied, i.e. for binary numbers it is always 2 to the power of n -1 , where n is the number of the digit, respectively, neither 30 nor 10 can be a weight for the digit of a binary number, because they are not powers of two
