Answer 1

Hey buddy here's your answer...

6 to the power n can not end with digit 0 for any natural number n.

$6 {}^{n \: } can \: be \: written \: in \: form \: (2 \times 3) {}^{n}$

6 has 2 and 3 as it's factors.

But a number ending with 0 has both 2 and 5.

So,6 to the power n can not end with digit 0
