I am really sorry.......... .

Answer 2

Answer:

There is very simple rule for finding unit’s digit -

There is very simple rule for finding unit’s digit -Consider only unit’s place digit in base no. Which is 4 in this case. ( here base no. is 264)

There is very simple rule for finding unit’s digit -Consider only unit’s place digit in base no. Which is 4 in this case. ( here base no. is 264)Now remember powers of some no.s as-1^any power = 1

There is very simple rule for finding unit’s digit -Consider only unit’s place digit in base no. Which is 4 in this case. ( here base no. is 264)Now remember powers of some no.s as-1^any power = 13^4 = 1

There is very simple rule for finding unit’s digit -Consider only unit’s place digit in base no. Which is 4 in this case. ( here base no. is 264)Now remember powers of some no.s as-1^any power = 13^4 = 14^even no. = 6

4^odd no. = 4

4^odd no. = 45^any power = 5

4^odd no. = 45^any power = 56^any power = 6

4^odd no. = 45^any power = 56^any power = 67^4 = 1

4^odd no. = 45^any power = 56^any power = 67^4 = 13. So, here the question is (264)^102

4^odd no. = 45^any power = 56^any power = 67^4 = 13. So, here the question is (264)^102That is case of - 4^even no.

4^odd no. = 45^any power = 56^any power = 67^4 = 13. So, here the question is (264)^102That is case of - 4^even no.Hence ansswer is 6.
