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
