0^0 = 1
1^1 = 1
2^2 = 4
3^3 = 27
4^4 = 256
5^5 = 3125
6^6 > 6*3125 > 9999 hence a,b,c,d are all 0-5

one of the numbers must be a 5 to make it a 4 digit number in the first place (if all digits were 4 then it would be 1024 which doesnt match remotely)
a cannot be 4 or 5 because there would be no way to get from 3125 to 4000s or 5000s with the other 3 digits

by those 2, a = 3

using a bit more logic we get the number being 3435, but that's just unnecessary
