a=bq+r
n=0,1
12^n = (2*2*3)^n
=2(1*1*3)^0
= 2 therefore it ends with 2
=2(1*1*3)^1
=2*2*3
=12 therefore ends with 12
=2(1*1*3)^2
=2*9
=18 therefore ends with 18
therefore 12^n cannot end with 0 or 5

Answer:
Step-by-step explanation:
No it will not end with the digit 0 and 5 because,prime factorisation of 12 is not of the form 2^n5^m,where n,m are non-negative integer.
