The units digit of the expression $$25^{6251} + 36^{528} + 73^{54}$$ is
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 $$(3)^{54}=(3)^{4\times13+2}=(3)^2=9$$
Thus, sum of unit digits = $$5+6+9=20$$
Thus, $$0$$ is the unit digit of above expression.
