If question is asking to find the remainder when 38^(n+3) +2 is divided by 5
then there is no single answer
Put n=1, then unit digits of 38^4 =6. then the unit's digit of the number =8.Therefore, the remainder would be 3
put n=2, unit digits of 38^5=8, then unit digits of the number=0. therefore there would be no remainder.
