Question

check whether 6 n can end with the digit 0 for any natural number

Answer 1

here is her answer ...

if any no. ends with 0 so it could be divided 10.

in other words we can also divided as 2 or 5 also..

so the prime factorisation on 6n is ( 2*3)n .

so If u know that 5 is not the factorisation of 6n ...

so we can say that 6n cannot end with 0 for any natural number.

hope this will help you ...⭐⭐⭐

-- :

If any digit has the last digit 10 that means it divisible by 10.

The factor of 10=2×5,

So value of 6^n should be divisible by 2 and 5.

Both 6^n is divisible by 2 but not divisible by 5.

So, it can not end with 0.
