How to find 4's complement of 7 base 10
How to find 4's complement of $7_{10}$? Approach 1: Convert to base4 and find its radix complement $7_{10} = (13)_4$ Radix complement(4's complement) = $21_4 = 9_{10}$ (result) Approach 2: Convert to base5 and find its diminished ... complement (4's complement) = $(32)_5 = (17)_{10}$ (result) Are these approaches correct? If yes, why different results?!
