• when we multiply 31*31 we get in units digit value=1
  again when we multiply the number which contains in unit digit 1 1034 times we get always 1 in unit digit

• (a^m)^n=(a^mn) then (31)^431*1034
  there in power we have 4 in the unit place.
  and (31)^---4 so (1)^4 so the answer is 1.

• Solve like this:
  
  1034%4=43
  431 * 2=862%10=2
  2%4=2
  So,31^2=gives unit digit 1

• last digit = 1 So unit digit will be 1. As we know 0,1,5,6 , whenever this digits are in unit place, whatever be the power, the unit place will be the same digit. Always remember this concept.
