What will be the unit digit of 1122^1122!

• 1122! is a multiple of 4 as it contains 00 at the last two digit.
  Now, using 4n rule.
  4n+1 = ..2 (2^1=2)
  4n+2=.. 4 (2^2=4)
  4n+3=.. 8 (2^3=8)
  4n= ... 6(2^4=16)
  AS 1122! is multiple of 4
  Hence unit digit will be 6

• ans is 4
  bcoz 1122^1122 is similar if we take 2^1122
  now 2 has only 4 digits as last digits
  i.e. 2
  4
  8
  6
  then these digits are repeated so divide 1122 by 4 and remainder is 2 therefore
  ans is 4

• 1122^1122! can be written as (4^3!)^187!
  when compared to the unit digit 4^3 the the 4 is obtained.
  
  so answer is 4

• There is a property of factorial. Is that all the number greater then 4! Always divisible by 4 and always will be even. So 1122!%4 =0 that means repeation in 2 power is 2,4,8,6 means there is 0 remainder in 1122%4 so when there is no remainder in power of a number then we choose last repeated digit of 2 so 6 is last repeated digit
  
  Hence ans is 6
