Find the unit's digit in (264)^102 + (264)^103 Choose the correct option
A) 0
B) 2
C) 5
D) 3
E) 4
Required unit's digit = unit's digit in (4)^102 + (4)^103.   Now, 4^2 gives unit digit 6.   (4)102 gives unjt digit 6.   (4)103 gives unit digit of the product (6 x 4) i.e., 4.   Hence, unit's digit in (264)m + (264)103 = unit's digit in (6 + 4) = 0.   0nswer is 0
