what is reminder when 6^17 + 17^6 divided by 7?
1)1
2)6
3)0
4)3

• remainder is 1
  6^17 gives unit no. is 6 and 17^6 gives unit no. 9
  then 9+6=15
  15%7=1

• ans:0
  6^17 + 17^6=(7-1)^17 + (10+7)^6=7*n+1000000-1=7*n+999999=7*n+7*142857=7*(n+142857)

• 7^16+16^7)/7
  =7 divide by 7 gives 0 remainder and 16 divide by 7 gives 2 as remainder
  So,
  = (0^16 + 2^7)/7
  = (0 + 128)/7
  = 128/7
  So remainder will be: 2

• ans:0
  as 6%7=(-1)&(-1)^17=-1 i.e 6
  &17^6%7=3^6%7 =2^3%7=1
  hence,6+1%7=0
