Find the unit's digit in (264)^102 + (264)^103	Choose the correct option.
A) 4	B) 1	C) 5	D) 0	E) 2
Required unit's digit = unit's digit in (4)^102 + (4)^103.   Now, 4^2 gives unit digit 6.   Therefore, (4)^102 gives unit digit 6.   Therefore, (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.   Answer is 0.
