The unit digit of (124)^372 + (124)^373 is


This is reply by AI


Unit digit of a number with power always moves in a circular manner

For eg in this case,
unit digit of 4^1 = 4
4^2 = 16 so 6
4^3 = 64 so 4
4^4 = 256 so 6
Therefore we can see that unit digit of 4 moves in a cycle of 2 with even powers having unit digit as 6 and odd having unit digits as 4

therefore here, it would be 6 + 4 = 0

Hence, 0 would be the answer
