• The question is (6^17+17^6) /7 !!!!
  remainder is 7 !!
  the solution is => from remainder cycles of 6 6^17 / 7 = 6 and from fermat little theorem 17 ^ 6 / 7 =1 . so, 6 + 1 =7 .
  there fore 7 is the solution!!!

• 0 ans: as 6/7 rem is -1 and -1^17 =-1 then 17/7 rem is 1 and 1^6 =1 so -1 =1=0

• The question is (6^17+17^6) /7 !!!!
  remainder is 0 !!
  the solution is => from remainder cycles of 6 6^17 / 7 = 6 and from fermat little theorem 17 ^ 6 / 7 =1 . so, 6 + 1 =7 .
  and now 7%7=0 so option 3
  is correct.

• By remainder theorem,(617%7)+(176%7)=(1+2)%7=(3%7)=3
  So,remainder=3.
