Subtract in the indicated base 51216 15206 51216 15206 Sol

Subtract in the indicated base. 5121_6 - 1520_6 5121_6 - 1520_6

Solution

Given 5121₆-1520₆

1-0 is 1

2-2 is 0

Since 5 cannot be subtracted from 1, 6 (sice the base is 6) is borrowed from the 5 before it.

So we get 7-5 is 2

Since 6 is borrowed, we reduce 1 from 5 so 4 remains

Therefore 4-1 is 3

Hence the answer is 3201₆
