```										Dear sundeep
to know digit at unit place we do not need whole number
just take the digit at unit place ie 3
digit at unit place
3^1 =                  3
3^2 =                  9
3^3 =                 7
3^4=                  1
3^5=                  3

digit at unit place is periodic of period 4

digit at unit place for 23)^14  =is same as digit at unit place for 3^2
that is 9
