Question 5

Find the unit digit in(1234)102+(1234)103

Accepted Answer

The unit digit of 1234 is 4. The cyclicity of 4 is 2 (4^1=4, 4^2=16). For 4^102, 102/2 leaves remainder 0, so unit digit is 6. For 4^103, 103/2 leaves remainder 1, so unit digit is 4. Summing 6+4 gives 10, so the unit digit is 0.
