wht is reminder whn 6^17+17^6 is devided by 7?

• short method:
  first take powers
  17-1/4=16/4==>remainder=0==>so 6^0+1=units digit 6
  6-1/4=5/4==> reaminder =1==> so 17^1+1= units digit 9
  
  Now, add units digits=6+9=15
  
  so final units digit is 5
  
  which absolutely divisible 7
  
  
  So, ans is "0"
