what is the remainder when 4^5^6^7 + 1 is divided by 10?

  4^5 ends wid 4
  4^6 ends wid 6
  6^7 ends wid 6
  6+1=7

• since 4^5^6^7=4^210, or it may express as (4^2)^105=16^105 so last digit =6 and+1=7 so answer=7

• ((4)^210)/10 + 1/10 (ie..5*6*7=210)
  4^1/10->6 remainder
  4^2/10->4 remainder
  4^3/10->6 remainder
  4^4/10->4 remainder
  so for even number power when divided by ten leads 4 as a remainder
  when 1/10 leads 1 as a remainder
  so...4+1=5 is the remainder

• 4^5*6*7=4^210
  210%4=2
  4^2+1
  17%10=7
  so 7 is answer
