Unit digit of 5 raised to any power = 5 Similarly, unit digit of 6 raised to any power = 6 Expression : $$25^{6251} + 36^{528} + 73^{54}$$ Now, unit digit of $$(3)^{54}=(3)^{4 imes13+2}=(3)^2=9$$ Thus, sum of unit digits = $$5+6+9=20$$ Thus, $$0$$ is the unit digit of above expression. => Ans - (D)
