Question

$\huge \boxed{\fcolorbox{red}{yellow}{❥ Question}}$
Check whether 4n can end with the digit 0 for any natural number n.

Answer 1

For unit's digit to be 0, then 4n should have 2 and 5 as its prime factors, but

$\huge \leadsto \sf \color{olive}( {2})^{2}n$

It does not contain 5 as one of its prime factors.

Hence, 4n will not end with the digit 0.

Thank you for the question.
