Number System - Place Value

Question

Determine the place value (weight) of each digit in a five-digit number in base-8 (octal).

Answer 1

Decimal and Octal are positional number systems. So, a number has a "weight" associated with it because of its position. For example, the "3" in 342 has a value different from the "3" in 423.

The "weights" are powers of the number base (base 10 or base 8) being used. So, 423₁₀ is different from 423₈.

In decimal, this is four hundred twenty three (base 10)::

But in Octal, this is:

423₈ (?? Do we have words to decribe this ??)

The first row of this table has the weights. Extend it for five-digit numbers.
