Answer:
Step-by-step explanation:
You can do this in a conventional mathematics way by showing each digit as an increasing power of 8, starting with zero
E.g 325 octal
(3 * 8 2 ) + (2 * 8 1 ) + (5 * 8 0 ) = (3 * 64) + (2 * 8) + (5 * 1)
i.e 192 + 16 + 5 = 197 decimal
Note: any number raise to power of 0 in indices is equal to 1
